- 2. User Input Every Program should have some sort of User interaction, for example a value for a variable. The User will enter one or more values to store in Memory Locations. This is similar to referencing the variable in the Memory and putting the Value in it. Syntax int n; scanf(“%d”,&n); scanf: is the Function responsible for taking user input. %d: format specifier for taking the input value format Examples #include <stdio.h> int main() { int ascii; // declaration only printf("Enter the ASCII decimal: "); scanf("%d",&ascii); printf("The Character is: %c",ascii); return 0; } #include <stdio.h> int main() { float marks; // declaration only printf("Enter the Marks in float: "); scanf("%f",&marks); printf("Obtained Marks: %0.2f",marks); return 0; }
