Input-Output in C In this post, we will learn how to take an input from terminal and display/print on the terminal. We take a input from the terminal to fill dynamic value in a variable. Introduction In c programming, we scanf() function to take an input from terminal and printf() function to displace value of a variable on the terminal. Integer Input-Output in C program In C programming we use scanf() function with parameters %d and &variable_name to take an integer input from the terminal and printf() function to print the variable value on the terminal. #include <stdio.h> int main() { int variable; scanf("%d", &variable); printf("%d", variable); return 0; } In above example, int variable; means decler a variable with name variable you can keep any name scanf("%d", &variable); means take a input from termial-keyboard and strore in variable variable printf("%d", variab...
