C Programming

This is the program for this problem, but i don't know where to place printf statement so that it asks "Enter 20 integers: ". please help. How do I make it ask for integers as soon as I run the proplem??

#include

int checkDuplicate(int arr[], int num, int count)

{

int i;

for (i = 0; i

if (arr[i] == num)

return 1;

}

return 0;

}

int main(void) {

printf("Enter 20 integers: ");

int arr[20];

int num, c = 0, i;

for (i = 0; i

scanf_s("%d", &num);

if (checkDuplicate(arr, num, c) == 0) {

arr[c] = num;

printf("%d ", num);

c++;

getchar();

}

}

return 0;

}

Problem (Duplicate Elimination) Use a one-dimensional array to solve the following problem. Read in 20 numbers, each of which is between 10 and 100, inclusive. As each number is read, print it only if it's not a duplicate of a number already read. Provide for the "worst case" in which all 20 numbers are different Use the smallest possible array to solve this
