Question

Questions:

1) What is the difference between "puts" and "printf" functions in C programming? Write a program to show the difference.

2) Why is the "getch()" function in C not working?​

Answer 1

Answer:

1) printf prints whatever you provide, it may be text, text + values etc without adding new line after the text while puts add one more character that is new line character (\n) just after the text/character stream.

2) getch() is a nonstandard function and is present in conio.h header file which is mostly used by MS-DOS compilers like Turbo C. It is not part of the C standard library or ISO C, nor is it defined by POSIX.

Like these functions, getch() also reads a single character from the keyboard. But it does not use any buffer, so the entered character is immediately returned without waiting for the enter key.

1. printf prints whatever you provide, it may be text, text + values etc without adding new line after the text while puts add one more character that is new line character (\n) just after the text/character stream.
2. #include <stdio.h>

#include <conio.h>

int main(void){

char str[] = "This is the end";

printf("%s\n", str);

getch(); //I tried getchar() also still does not work

return 0;
