Converting a string to a float in C

To convert a string to a float in C, you can use the atof() function from the C standard library. This function takes a string as input and returns the corresponding floating-point value.

Here's an example of how you can use the atof() function:

#include <stdio.h>
#include <stdlib.h>

int main() {
    char str[] = "3.14";
    float num = atof(str);
    printf("The converted float value is: %f\n", num);
    return 0;
}

In this example, the string "3.14" is converted to a float using the atof() function, and the result is stored in the variable num. The converted float value is then printed using printf().

Please note that the atof() function returns 0.0 if the input string cannot be converted to a float.

I hope this helps! Let me know if you have any further questions.
