c how to get an integer from user input
To get an integer from user input in the C programming language, you can use the scanf
function. Here's an example:
#include <stdio.h>
int main() {
int num;
printf("Enter an integer: ");
scanf("%d", &num);
printf("You entered: %d\n", num);
return 0;
}
In this example, the scanf
function is used to read an integer from the user and store it in the variable num
. The %d
format specifier is used to indicate that an integer should be read. The &
operator is used to get the address of the variable num
so that scanf
can store the input value there. Finally, the entered integer is printed using printf
.
Please note that the above code assumes that the user will enter a valid integer. If the user enters something other than an integer, the behavior of the program may be unpredictable. It's a good practice to validate user input to ensure it matches the expected format.
I hope this helps! Let me know if you have any further questions.
