Inbuilt Functions

i).  Functions to manipulate strings

The cstring library defines many functions to perform some manipulation operations with C-styled functions. The following are some of these functions:

  • strcat: char* strcat (char* dest, const char* src); Appends src string at the end of dest string.
    Returns dest.
  • strcmp: int strcmp (const char* string1, const char* string2); Compares strings string1 and
    string2. Returns 0 is both strings are equal.
  • strcpy: char* strcpy (char* dest, const char* src); Copies the content of src to dest. Returns dest.
  • strlen: size_t strlen (const char* string); Returns the length of string.

ii). Converting strings to other types

Due to that a string may contain representations of other data types like numbers it might be useful to translate that content to a variable of a numeric type. The cstdlib library provides three useful functions for this purpose:

  • atoi: converts string to int type.
  • atol: converts string to long type.
  • atof: converts string to float type.

All of these functions accept one parameter and return a value of the requested type (int, long or float).
