char* strchr( char* str, int ch ); |
Finds the first occurrence of the character static_cast<char>(ch)
in the byte string pointed to by str
.
The terminating null character is considered to be a part of the string and can be found if searching for '\0'
.
str | - | pointer to the null-terminated byte string to be analyzed |
ch | - | character to search for |
Pointer to the found character in str

#include <cstring> #include <iostream> int main() { const char *str = "Try not. Do, or do not. There is no try."; char target = 'T'; const char *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.'
