Answer :

#include<stdio.h>

int main ()

{

int a,b,sum=0,r,c;

int x[100][100];

printf("Enter the number of row of the matrix : ");

scanf("%d",&a);

printf("Enter the number of the column : ");

scanf("%d",&b);

for (r=1;r<=a;r++)

{

for (c=1;c<=b;c++)

{

printf("Enter the elements of the Matrix %d%d : ",r,c);

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

}

}

printf("The Enter matrix is \n");

for (r=1;r<=a;r++)

{

for (c=1;c<=b;c++)

{

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

}

printf("\n");

}

printf ("The sum of the element of matrix is : ");

for (r=1;r<=a;r++)

{

for (c=1;c<=b;c++)

{

sum=sum+x[r][c];

}

}

printf("%d",sum);

}


Output :
