Sum of all element in matrix by R4R Team

Matrix:
-Multidimensional Array
-Matrix consist of the rows and columns.

Syntax-
array[row][column]
//Martix with numbers of rows and columns

Example-
Matrix is:
1 2
4 3
Sum of all elements in array is 10

program-

#include< stdio.h>
int main()
{
int a[10][10],r,c,i,j,sum=0;
printf("Enter rows and columns in matrix\n");
scanf("%d%d",&r,&c);
printf("Enter %d number in matrix\n",r*c);
//input in matrix
for(i=0;i< r;i++){
for(j=0;j< c;j++)
{
scanf("%d",&a[i][j]);
}
}
printf("Matrix is\n");
for(i=0;i< r;i++){
for(j=0;j< c;j++)
{
printf("%d ",a[i][j]);
}
printf("\n");
}
//Now find sum
for(i=0;i< r;i++)
{
for(j=0;j< c;j++)
{
sum=sum+a[i][j];
}
}
printf("Sum of all number in Matrix is %d",sum);
}


output-

Enter rows and column in matrix
2 3
Enter 6 number in matrix
1 2 3 4 5 6
Matrix is
1 2 3
4 5 6
Sum of all number in Matrix is 21
