How to use scanf in C
A lot of new C programmers have trouble with scanf(). So I'm going to show you how to implement scanf in C in this tutorial.
The main reason beginners have trouble is scanf works like a pointer so you have to point to what you are getting input for Code:
#include<stdio.h> int main() { int myvariable; printf("Enter a number:"); scanf("%d",&myvariable); printf("%d",myvariable); return 0; } "%d" for int ,"%f" for float ,"%e" for a scientific notation (1e10) ,"%c" for char , "%s" for strings. Then in the second part we have to use & just like in a pointer to point to the variable instead of just getting its value. Remember without & your program will likely crash. For handling strings with whitespace (sentences) and in files use fgets. Here is one of our tutorials on using it: Reading And Writing Files In C. You can bookmark or print the manual page on scanf for later reference: Scanf() - C reference

Nice post. Thanks for sharing.
Scanf Function is basically used to get the input value from the user.
