Here is a simple C program that uses the `extern` storage class to find the smallest of three numbers: ```c #include extern int find_smallest(int num1, int num2, int num3); int main() { int num1, num2, num3; printf("Enter three numbers: "); scanf("%d %d %d", &num1, &num2, &num3); printf("Smallest number is %d", find_smallest(num1, num2, num3)); return 0; } int find_smallest(int num1, int num2, int num3) { int min = num1; if(num2

Question

Here is a simple C program that uses the `extern` storage class to find the smallest of three numbers:

```c
#include <stdio.h>

extern int find_smallest(int num1, int num2, int num3);

int main() {
    int num1, num2, num3;
    printf("Enter three numbers: ");
    scanf("%d %d %d", &num1, &num2, &num3);
    printf("Smallest number is %d", find_smallest(num1, num2, num3));
    return 0;
}

int find_smallest(int num1, int num2, int num3) {
    int min = num1;
    if(num2 < min)
        min = num2;
    if(num3 < min)
        min = num3;
    return min;
}
```

In this program, the `find_smallest` function is declared at the beginning with the `extern` keyword, which means that its definition can be found elsewhere, not necessarily before `main`. The function is then defined after `main`. It takes three integers as arguments and returns the smallest one. The `main` function reads three numbers from the user, calls the `find_smallest` function with these numbers as arguments, and prints the result.
