02

Example code

Here's a sample code demonstrating the usage of atoi() and atof() functions with the appropriate inclusion of the header file: ```c #include #include int main() { char num_str1[] = "123"; char num_str2[] = "456.78"; int num_int = atoi(num_str1); float num_float = atof(num_str2); printf("Converted integer: %d\n", num_int); printf("Converted floating-point number: %.2f\n", num_float); return 0; } ``` In this example, the `` header file is included to access the atoi() and atof() conversion functions, which convert the string representation of numbers into their int and float equivalents respectively.
