Answer-

Test Data :

Input 5 elements in the array :

element - 0 : 12

element - 1 : 14

element - 2 : 22

element - 3 : 4

element - 4: 9

Expected Output :

Your Array Element is: 12, 14, 22, 4, 9

#include<stdio.h>

#include<conio.h>

void main()

{

int A[5];

int a;

printf(“Enter Elements of array\n”);

for(a=0; a<5;a++)

{

printf(“\nEnter %d Element of Array: ”,a);

scanf(“%d”,&A[a]);

}

 printf(“Your Array Element is :”);

for(a=0; a<5;a++)

{

printf(“%d ,”,A[a]);

}

getch();

}
