String Functions are the built-in functions provided by CPP to operate and manipulate a string. CPP provides a number of string functions. Some of the MOST USED string functions are listed below:
| FUNCTION | SYNTAX | USES |
| strcpy() | strcpy(destination, source) | Copies a string from source to destination. |
| strcat() | strcat(string1, string2) | Concatenates two strings. |
| strcmp() | strcmp(string1, string2) | Compares two strings, if same, it returns 0. |
| strlen() | strlen (string name) | Returns the length of a string. |
Example:
#include <iostream.h> #include<cstring.h> using namespace std; int main( ) { char chr1[] = "ROSE"; char chr2[10]; int l2 = strlen(chr1); cout << "Hint: Number of words in my favourite flower name is: " << l2 <<endl; cout << "Enter the name of my favourite flower: "; cin >> chr2; if (strcmp (chr1, chr2) == 0) cout << "Right Answer!!"; return 0; } |
Output
Hint: Number of words in my favourite flower name is: 4 Enter the name of my favourite flower: ROSE Right Answer!! |
