**Write a Modular C Programming Code for Sum & Avg 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); int SumMatrix(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); sum=SumMatrix(a,r,c); printf("The SUM of the Matrix is: %d\n",sum); avg=(double)sum/r*c; printf("The Avg of the Matrix is: %lf\n",avg); } 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"); } } int SumMatrix(int a[ROW][COL], int r, int c) { int i,j,sum=0; for(i=0;i<r;i++) { for(j=0;j<c;j++) { sum=sum+a[i][j]; } } return sum; }

**OUTPUT**

Enter the order of 2D matrix: 2 3 Enter the Elements of Matix: 5 3 2 6 4 2 The Elements of Matix are 5 3 2 6 4 2 The SUM of the Matrix is: 22 The Avg of the Matrix is: 33.000000 Process returned 0 (0x0) execution time : 13.563 s Press any key to continue.
