Question

Write a c program for adding two matrices of 3x3 using pointers.

Answer 1

Explanation:

/*source code of addition of 3x3 matrix c program*/

#include<stdio.h>

#include<conio.h>

int main()

{

int matA[3][3],matB[3][3],matC[3][3];

int r,c,k;

for(r=0; r<3; r++)

{

for(c=0; c<3; c++)

{

printf("Enter first matrix : ");

scanf("%d", &matA[r][c]);

}

}

for(r=0; r<3; r++)

{

for(c=0; c<3; c++)

{

printf("Enter second matrix : ");

scanf("%d", &matB[r][c]);

}

}

for(r=0; r<3; r++)

{

for(c=0; c<3; c++)

{

matC[r][c]=0;

for(k=0; k<3;k++)

matC[r][c] = matA[r][c] + matB[r][c];

}

}

printf("\n New addition matrix : \n");

for(r=0; r<3; r++)

{

for(c=0; c<3; c++)

printf(" %d",matC[r][c]);

printf("\n");

}

getch();

return 0;

}
