Why does the last printf create new lines after each placeholder?

Question

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

int main()
{
    char name [50];
    char age [50];

    printf("Please enter your name:\n");
    fgets(name, 20, stdin);

    printf("Please enter your age:\n");
    fgets(age, 20, stdin);

    printf("Hello %s, you are %s years old", name, age);

    return 0;
}

//sorry for such a trvial question I am new to programming, but Why does the last printf create new lines after each placeholder?

You are getting input from stdin, so you are probably ending your entries by hitting Enter: therefore you end your line with the \n character and fgets() stores it into the name and age variables.

Not ”probably”. For all practical purposes, it's a certainty that the inputs are terminated with a newline which is causing the line breaks in the output. – Jonathan Leffler Sep 26 '20 at 21:19
