C++ examples for Data Type:char array
Use strtok( ) to tokenize a null-terminated string:
#include <iostream> #include <cstring> using namespace std; int main() {/* w w w. jav a2 s. c o m*/ // First, use strtok() to tokenize a sentence. char delims[] = "., ?;!"; char str[] = "I like apples, pears, and grapes. Do you? this is a test"; char *tok; cout << "Obtain the words in a sentence.\n"; // Pass the string to be tokenized and get the first token. tok = strtok(str, delims); // Get all remaining tokens. while(tok) { cout << tok << endl; // Each subsequent call to strtok() is passed NULL for the first argument. tok = strtok(NULL, delims); } // use strtok() to extract keys and values stored in key/value pairs within a string. char kvpairs[] = "count=10, name=\"abc, jr.\", max=100, min=0.01"; // Create a list of delimiters for key/value pairs. char kvdelims[] = " =,"; cout << "\nTokenize key/value pairs.\n"; // Get the first key. tok = strtok(kvpairs, kvdelims); // Get all remaining tokens. while(tok) { cout << "Key: " << tok << " "; if(!strcmp("name", tok)) { tok = strtok(NULL, "\""); } else { tok = strtok(NULL, kvdelims); } cout << "Value: " << tok << endl; // Get the next key. tok = strtok(NULL, kvdelims); } return 0; }
