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.
