C Program.Thanks!

Problem 5: Pointer (20%) Please modify the program below and change the value in each variable in increasing order. Requirement: 1. Should not modify the existed code. 2. You can only add one function call in the main function. 3. You can only declare at most two functions in the program. 4. The function should not return any value or print any result. 5. The inputs of the function are only relative to a, b and c that declared in main function. 6. Digital number is not allowed to appear in the function definition. #include // add function declaration here with function name "func" int main() { int a, b, c; scanf(" %d %d %d", &a,&b, &c); //add only one function here printf ("a=%d, b=%d, c=%d ", a, b, c); return 0; } // add function definition here Example: Input 381 940 Output a=1, b=3, c=8 a=0, b=4, c=9
