In the C Programming Language, the atof function converts a string to a floating-point number. The atof function skips all white-space characters at the beginning of the string, converts the subsequent characters as part of the number.
atol() Function The function atol() converts string into a long integer. It returns zero, when no conversion is performed. It returns the converted long int value. Here is the syntax of atol in C++ language, long int atol(const char *string) Here is an example of atol() in C++ langu...

Each function returns thedoublevalue produced by interpreting the input characters as a number. The return value is 0.0 if the input can't be converted to a value of that type. In all out-of-range cases,errnois set toERANGE. If the parameter passed in isNULL, the invalid parameter handle...
In general, a valid floating point argument for atof() function has the following form: [whitespace] [- | +] [digits] [.digits] [ {e | E }[- | +]digits] The atof() function ignores all the leading whitespace characters until the primary non-whitespace character is found. Then, begi...
