Question
Chapter 12.3, Problem 12.11CP
Program Plan Intro
“atof” function:
In C++, the predefined function “atof” is used to convert a string value into a double-precision floating point value; it passes a string literal or character array as an argument and it converts the received value into a double type value; it takes only one parameter as an argument.
- If the argument value contains nonconvertible contents combined with the integer value then the values will be ignored while converting.
- In same way, the function will return “0” when the values can’t be able to convert into double data type.
Syntax:
Syntax for the “atof” function is as follows:
double atof (const char* n);
In the above statement,
- “double” represents the return type of the function.
- “atof” represents the name of the function.
- “const char*” represents the data type of the passing argument.
- “n” is a string variable which is required to be converted.
Example:
The example for the “atof” function is as follows:
//change the string literal to a double value.
double n = atof ("1258.11E-14 ");
In the above line, the string literal “1258.11E-14” is passed as an argument to “atof” and it returns the converted value that is “1.25811e-11”.
