Let first we some topic Receiving input from the user In order to take input from the user and assign it to a variable, we use scanf function. The syntax for using scanf: scanf("%d",&a); // %d for integer // %f for real constant // %c for character & is the “address of” operator and it means that the supplied value should be copied to the address which is indicated by variable i. Here the code--> #include <stdio.h> int main(void) {     int n;     scanf("%d",&n);     printf("%d",n); return 0; } The logic is very easy that first we declare a integer then take a input through user by using scanf then print that variable.                                                Thank You
