Question

In this example you are allowed to use from the C standard library only functions for input and output (e.g. printf(), scanf())

For this exercise you should be able to write a logical expression (i.e., with logical operators) which checks if some integer x consists of exactly 5 digits. Ex: 30498 and -14004 are 5-digit numbers, while 1018, -2 and 46 are not.

Complete the intQ2(intQ2_input) function that takes an input integer parameter and returns 1 if the number is five digits and 0.

Answer 1

Answer;

Explanation:

Here is the function in Bold below which takes an integer input and then counts the number of digits present in that number.

If the digits are 5, it returns 1

Otherwise it returns 0.

Code:

#include <stdio.h>

int intQ2(int intQ2_input)
{
int digits = 0;
  
if(intQ2_input<0)
intQ2_input = -intQ2_input;
  
while(intQ2_input>0)
{
intQ2_input = intQ2_input/10;
digits = digits + 1;
}
  
if(digits==5)
return 1;
else
return 0;
}
int main()
{
printf("%d", intQ2(-14004));

return 0;
}
