Write a C program to insert an element in an array at the desired position.
int main() {
int data[100], i, n, pos, ele, flag = 0;
/* get the number of elements from the user */
printf("Enter the number of elements:");
scanf("%d", &n);
/* get the entries from the user */
printf("Enter your inputs:\n");
for (i = 0; i < n; i++)
scanf("%d", &data[i]);
while (1) {
/* get the position and element from user */
printf("Enter the pos & element to insert:\n");
scanf("%d%d", &pos, &ele);
/* inserting the new element */
if (pos < 0 || pos > n + 1) {
printf("Wrong input for position!!\n");
} else {
for (i = n; i >= pos; i--)
data[i] = data[i - 1];
data[pos - 1] = ele;
n++;
}
/* display the results */
printf("After insertion operation:\n");
for (i = 0; i < n; i++)
printf("%d ", data[i]);
printf("\nDo you want to continue(0/1):");
scanf("%d", &flag);
if (!flag)
break;
}
return 0;
}
Output:
jp@jp-VirtualBox:~/$ ./a.out
Enter the number of elements:5
Enter your inputs:
100 200 300 400 500
Enter the pos & element to insert:
3 250
After insertion operation:
100 200 250 300 400 500
Do you want to continue(0/1):0
