c language float user input

To take a float input from the user in C language, you can use the scanf function along with the %f format specifier. Here is an example code snippet:

#include <stdio.h>

int main() {
    float num;

    printf("Enter a float number: ");
    scanf("%f", &num);

    printf("You entered: %f\n", num);

    return 0;
}

In this code, we declare a variable num of type float to store the user input. The printf function is used to display a message asking the user to enter a float number. Then, the scanf function reads the user input and stores it in the num variable using the %f format specifier. Finally, we use the printf function again to display the value entered by the user.

You can run this code and try entering different float values to see how it works. Remember to include the stdio.h header file at the beginning to use the printf and scanf functions.
