Data Type Solution in C Programming

This Page Contains the Solution in C Programming Language for the Day 1 : Data Type, Code Challange of the HackerRank 30 Days of Code.

#include <stdio.h>
#include <string.h>
#include <math.h>
#include <stdlib.h>

int main() {
    int i = 4;
    double d = 4.0;
    char s[] = "HackerRank ";
    int i2;
    double d2;
    char s2[100]; // this is not scalable for input of unknown size
    // Read inputs from stdin
    scanf("%d", &i2);
    scanf("%lf", &d2);
    scanf("%*[\n] %[^\n]", s2); 
    // Print outputs to stdout
    printf("%d\n", i + i2);
    printf("%.01lf\n", d + d2);
    printf("%s%s", s, s2);
    return 0;
