constchar* strchr(constchar* str,int ch); | ||
char* strchr( char* str,int ch); | ||
Finds the first occurrence of the characterstatic_cast<char>(ch) in the byte string pointed to bystr.
The terminating null character is considered to be a part of the string and can be found if searching for'\0'.
Contents |
| str | - | pointer to the null-terminated byte string to be analyzed |
| ch | - | character to search for |
Pointer to the found character instr, or a null pointer if no such character is found.
#include <cstring>#include <iostream> int main(){constchar* str="Try not. Do, or do not. There is no try.";char target='T';constchar* result= str; while((result= std::strchr(result, target))!= nullptr){std::cout<<"Found '"<< target<<"' starting at '"<< result<<"'\n"; // Increment result, otherwise we'll find target at the same location++result;}}
Output:
Found 'T' starting at 'Try not. Do, or do not. There is no try.'Found 'T' starting at 'There is no try.'
