C Program
#include<stdio.h> int main() { int i, j, mat[10][10], row, col; int sum = 0; printf("\nEnter the number of Rows : "); scanf("%d", &row); printf("\nEnter the number of Columns : "); scanf("%d", &col); //Accept the Elements in Matrix for (i = 0; i < row; i++) { for (j = 0; j < col; j++) { printf("\nEnter the Element mat[%d][%d] : ", i, j); scanf("%d", &mat[i][j]); } } //Addition of all Elements for (i = 0; i < row; i++) { for (j = 0; j < col; j++) { sum = sum + mat[i][j]; } } //Print out the Result printf("\nSum of All Elements in Matrix : %d", sum); return (0); }
Result
Enter the number of Rows : 2 Enter the number of Columns : 2 Enter the Element mat[0][0] : 1 Enter the Element mat[0][1] : 1 Enter the Element mat[1][0] : 1 Enter the Element mat[1][1] : 1 Sum of All Elements in Matrix : 4
