Write a Modular C Programming Code to Sum each Row & Columns of a 2D Array?
CODE:
#include<stdio.h>
#define ROW 10
#define COL 10
void ReadArray(int [ROW][COL], int, int);
void DisplayArray(int [ROW][COL], int, int);
void SumEachRow(int [ROW][COL], int, int);
void SumEachCol(int [ROW][COL], int, int);
main()
{
int r,c,sum;
int a[ROW][COL];
double avg;
printf("Enter the order of 2D matrix: ");
scanf("%d%d",&r,&c);
printf("\nEnter the Elements of Matix:\n");
ReadArray(a,r,c);
printf("\nThe Elements of Matix are\n");
DisplayArray(a,r,c);
SumEachRow(a,r,c);
SumEachCol(a,r,c);
}
void ReadArray(int a[ROW][COL], int r, int c)
{
int i,j;
for(i=0;i<r;i++)
{
for(j=0;j<c;j++)
{
scanf("%d",&a[i][j]);
}
}
}
void DisplayArray(int a[ROW][COL], int r, int c)
{
int i,j;
for(i=0;i<r;i++)
{
for(j=0;j<c;j++)
{
printf("%d ",a[i][j]);
}
printf("\n");
}
}
void SumEachRow(int a[ROW][COL], int r, int c)
{
int i,j,sum=0;
for(i=0;i<r;i++)
{
sum=0;
for(j=0;j<c;j++)
{
sum=sum+a[i][j];
}
printf("Sum of %dth row is: %d\n",i,sum);
}
}
void SumEachCol(int a[ROW][COL], int r, int c)
{
int i,j,sum=0;
for(j=0;j<c;j++)
{
sum=0;
for(i=0;i<r;i++)
{
sum=sum+a[i][j];
}
printf("Sum of %dth Column is: %d\n",j,sum);
}
}
OUTPUT
Enter the order of 2D matrix: 3 3 Enter the Elements of Matix: 5 9 5 1 3 6 5 4 9 The Elements of Matix are 5 9 5 1 3 6 5 4 9 Sum of 0th row is: 19 Sum of 1th row is: 10 Sum of 2th row is: 18 Sum of 0th Column is: 11 Sum of 1th Column is: 16 Sum of 2th Column is: 20 Process returned 0 (0x0) execution time : 13.245 s Press any key to continue.
