Write a program that accepts a number as input, and prints just the decimal portion.

Olegator [25]

Answer:

There are 2 ways to do extract the decimal part: 

Explanation:

First method using number

int main() {

double num = 23.345;

int intpart = (int)num;

double decpart = num - intpart;

printf(""Num = %f, intpart = %d, decpart = %f\n"", num, intpart, decpart);

}

Second method using string:

#include <stdlib.h>

int main()

{

char* inStr = ""123.4567"";

char* endptr;

char* loc = strchr(inStr, '.');

long mantissa = strtod(loc+1, endptr);

long whole = strtod(inStr, endptr);

printf(""whole: %d \n"", whole);

printf(""mantissa: %d"", mantissa);

}
