c++ programs to find transpose of a matrix with function and without function

Write two C++ programs which asks user to enter number of rows and colums and calculate its transpose and display the result accordingly.
Note: One with function and one without Function
function prototype:
void calculate_transpose(int matrix[5][5], int rows, int cols);
    
First we have to clear about what is transpose of a matrix.
Its to replace the number of rows with number of colums and vice versa to make a new matrix.
for example
if a matrix 'A' has dimension 2X3  means 2 rows 3 colums then new transpose matrix 'T' will be 3X2

        1  2  3                     1    4    
A=   4  5  6              T=   2   5
                                       3   6

C++ Code:   Compiler Used:  CodeBlocks
Without Functioin

    #include<iostream>
    using namespace std;
    int main()
    {

    int matrix[5][5],transpose_matrix[5][5];
    int i,j,rows,cols;
    // Taking Input In Array

      cout<<"Enter Number of ROWS :";
      cin>>rows;

      cout<<"Enter Number Of COLS  :";
      cin>>cols;
       for( i=0;i<rows;i++){
           for( j=0;j<cols;j++)
           {
               cin>>matrix[i][j];
           }
          }

          cout<<"\n Matrix You Entered\n";

       for( i=0;i<rows;i++){
           for( j=0;j<cols;j++)
           {
               cout<<matrix[i][j]<<"     ";
           }
           cout<<endl;
          }



// Calculating Transpose of Matrix
    cout<<"\n\n\nTranspose of Entered Matrix\n";
       for( i=0;i<rows;i++){
           for( j=0;j<cols;j++)
           {
               transpose_matrix[j][i]=matrix[i][j];
           }
           cout<<endl;
          }


//Displaying Final Resultant Array
       for( i=0;i<cols;i++){
           for( j=0;j<rows;j++)
           {
               cout<<transpose_matrix[i][j]<<"    ";
           }
           cout<<endl;
          }

   return 0;
    }

Sample input Output

With Function C++ Code:
In this the same code is used but passing the 2D array to a function with size of rows and cols

    #include<iostream>
    using namespace std;

    void calculate_transpose(int matrix[5][5], int rows, int cols);
    int main()
    {

    int matrix[5][5];
    int i,j,rows,cols;
    // Taking Input In Array

      cout<<"Enter Number of ROWS :";
      cin>>rows;

      cout<<"Enter Number Of COLS  :";
      cin>>cols;
       for( i=0;i<rows;i++){
           for( j=0;j<cols;j++)
           {
               cin>>matrix[i][j];
           }
          }

          cout<<"\n Matrix You Entered\n";

       for( i=0;i<rows;i++){
           for( j=0;j<cols;j++)
           {
               cout<<matrix[i][j]<<"     ";
           }
           cout<<endl;
          }


//**********CALLING FUNCTION************//
      calculate_transpose(matrix,rows,cols);


   return 0;
    }

 void calculate_transpose(int matrix[5][5], int rows, int cols)
{    int i,j;
    int transpose_matrix[5][5];
    cout<<"\n\n\nTranspose of Entered Matrix\n";
       for(i=0;i<rows;i++){
           for( j=0;j<cols;j++)
           {
               transpose_matrix[j][i]=matrix[i][j];
           }
           cout<<endl;
          }

       for(i=0;i<cols;i++){
           for( j=0;j<rows;j++)
           {
               cout<<transpose_matrix[i][j]<<"   ";
           }
           cout<<endl;
          }

Cpp Function to Find Largest and smallest number in array

This Cpp tutorial contains

• Cpp array with random integer values
• Passing array to function
• if statement with in for loop
• Calculate result in function and display

 Compiler used: CodeBlocks Cpp Compiler

Write a program which generates some random number and store in array after it program pass array to a function which calculates maximum and minimum number in array and display it use any Cpp Compiler to code.

How program works

• Declare array of size 10
• Using for loop assign array indexes with random values between 1 and thousand
• Call the function and pass array and its size as argument
• Function declares two integers max and min and assign both integers with arrays first index value
• Then with in for loop there are two if condition first check is for minimum number and second check is for maximum number
• Finally program display the output values of both integers min and max

      Cpp Code

1.  #include <iostream>
2. #include <stdlib.h>
3. using namespace std;
4. void FindMaxMin(int *array, int size)
5. {        int min,max;
6.          min=max=array[0];
7.          for(int i=0;i<size;i++)
8.          {
9.              if(array[i]<min)
10.                min=array[i];
11.             else if(array[i]>max)
12.                max=array[i];
13.          }
14.  cout<<"Minimum Number  = "<<min<<endl;
15.  cout<<"Maximum Number = "<<max<<endl;
16. }
17. int main()
18. {
19.     int array[10];
20.     for(int i=0;i<=9;i++)
21.         {
22.          array[i]=rand()%1000+1;
23.          cout<<"array ["<<i<<"]"<<"= "<<array[i]<<endl;
24.         }
25.     FindMaxMin(array,10);
26. return 0;
27. }

hollow diamond using for loop c++ code user enter input size of diamond

write a c++ program which takes size of diamond and display hollow diamond using nested for loop and asterisk character.
Output should be look like bellow

 User can enter its desired size of diamond either even or odd

For Example
If user enters size of 3
3 lines of will be formed above middle and 3 lines will be formed below middle line

Concept used:

• Nested for loop
• if statement

c++ code:

#include<iostream> using namespace std; int main() { cout<<"Enter size of  Daimond:  ";     int size;   cin>>size;     int z=1;   for ( int i=0; i<=size; i++)   {     for (int j=size; j>i; j--)     {       cout<<" "; // printing space here     }     cout<<"*";  // printing asterisk here     if ( i>0)     {       for ( int k=1; k<=z; k++)       {         cout<<" ";       }       z+=2;       cout<<"*";     }     cout<<endl; // end line similar  to \n   }   z-=4;   for (int i=0; i<=size-1; i++)   {     for (int j=0; j<=i; j++)     {       cout<<" ";     }     cout<<"*";     for (int k=1; k<=z; k++)     {       cout<<" ";     }     z-=2;     if (i!=size-1)     {       cout<<"*";     }     cout<<endl;   } return 0; }

If user enter size equal to 10

Recommended: Dry run the code line by line it will help to understand quickly and also clear the working of nested for loop.

inverted triangle shape in c++ code using for loop

write a c++ program which displays an inverted triangle using nested for loop and asterisk character

Use any Compiler IDE you want.
Required Output should be look like below image.

 

Compiler used: CodeBlocks c++ Compiler
c++ code:

#include<iostream> using namespace std; int main() {      cout<<"\"Inverted Triangle Shape\"\n\n";   int w=6;    for(int g=0;g<9;g++)  {   cout<<"*";    // Displaying asterisk here  }   cout<<endl; // endl is for new line   for(int a=1;a<=3;a++)  {     for(int b=0;b<a;b++)    {     cout<<" ";    // displaying space here    }     cout<<"*";       for(int c=1;c<w;c++)      {       cout<<" ";      }       cout<<"*"<<endl;       w=w-2;  }   for(int e=1;e<=1;e++)  {     for(int f=4;f>=e;f--)    {     cout<<" ";    }     cout<<"*";  }   return 0; }

sample output

These kinds of programs are basic level program can be coded in more than one way it is recommended to change the logic of program and do experiment with the code for better understanding
