Write a Program to Sum of Two Matrix in C

#include <stdio.h> #include <conio.h> void main() {     int r, c, a[100][100], b[100][100], sum[100][100], i, j;     printf("Enter number of rows (between 1 and 100): ");     scanf("%d", &r);     printf("Enter number of columns (between 1 and 100): ");     scanf("%d", &c);     printf("\nEnter elements of 1st matrix:\n");     for(i=0; i<r; ++i)     {         for(j=0; j<c; ++j)         {             printf("Enter element a%d%d: ",i+1,j+1);             scanf("%d",&a[i][j]);         }      }     printf("Enter elements of 2nd matrix:\n");     for(i=0; i<r; ++i)      {         for(j=0; j<c; ++j)         {             printf("Enter element a%d%d: ",i+1, j+1);             scanf("%d", &b[i][j]);         }      }     // Adding Two matrices     for(i=0;i<r;++i)     {         for(j=0;j<c;++j)         {             sum[i][j]=a[i][j]+b[i][j];         }      }     // Displaying the result     printf("\nSum of two matrix is: \n\n");     for(i=0;i<r;++i)     {         for(j=0;j<c;++j)         {             printf("%d   ",sum[i][j]);             if(j==c-1)             {                 printf("\n\n");             }         }       }          getch(); }

Output of the Program

Enter number of rows (between 1 and 100): 2 Enter number of columns (between 1 and 100): 3 Enter elements of 1st matrix: Enter element a11: 2 Enter element a12: 3 Enter element a13: 4 Enter element a21: 5 Enter element a22: 2 Enter element a23: 3 Enter elements of 2nd matrix: Enter element a11: -4 Enter element a12: 5 Enter element a13: 3 Enter element a21: 5 Enter element a22: 6 Enter element a23: 3 Sum of two matrix is:  -2   8   7    10   8   6
