Write a program to input n x m matrix and find the sum of all numbers.
Answers
Answer:
hey... mate
Input : mat[] = {{1, 1, 2},
{2, 3, 3},
{4, 5, 3}}
Output : 18
The even occurring elements are 1, 2 and their number
of occurrences are 2, 2 respectively. Therefore,
sum = 1+1+2+2 = 6.
Input : mat[] = {{10, 20},
{40, 40}}
Output : 80

Write a program to input n x m matrix and find the sum of all numbers.
Explanation:
C Program to read n x m matrix and find sum of all elements of two dimensional array
#include <stdio.h>
#define MAXROW 10
#define MAXCOL 10
int main()
{
int matrix[MAXROW][MAXCOL];
int i,j,n,m;
int sum;
printf("Enter number of rows :");
scanf("%d",&n);
printf("Enter number of Columns :");
scanf("%d",&m);
printf("\nEnter 2d array elements :\n");
for(i=0;i< n;i++)
{
for(j=0;j<m;j++)
{
printf("Enter element [%d,%d] : ",i+1,j+1);
scanf("%d",&matrix[i][j]);
}
}
/*sum of all elements*/
sum=0;
for(i=0;i<n;i++)
{
for(j=0;j<m;j++)
{
sum+=matrix[i][j];
}
}
printf("\nSum of all elements : %d",sum);
return 0;
}
Output
Enter number of rows :3
Enter number of Columns :3
Enter 2d array elements :
Enter element [1,1] : 22
Enter element [1,2] : 11
Enter element [1,3] : 9
Enter element [2,1] : 6
Enter element [2,2] : 34
Enter element [2,3] : 43
Enter element [3,1] : 89
Enter element [3,2] : 45
Enter element [3,3] : 32
Sum of all elements : 291
