So it adds '\n' after your 4 letters, returning string_length+1. From Removing trailing newline character from fgets () input you can add @Tim Čas solution to your code. The line is still read with the fgets () function and after we remove the newline character.

WebNov 25, 2012 · 11 Answers. Use strlen to find the length of (number of characters in) a string. const char *ptr = "stackoverflow"; size_t length = strlen (ptr); Another minor point, note that ptr is a string literal (a pointer to const memory which cannot be modified). Its better practice to declare it as const to show this. WebApr 14, 2024 · std::string str = "Be careful!"; int len = std::strlen (str.c_str ()); // Note: The pointer obtained from c_str () may only be treated as a pointer // to a null-terminated character string if the string object does not contain // other null characters.

WebMay 7, 2013 · int length (const char* str) { int i = 0; for (; * (str + i) != 0; i++); return i; } Now, instead of using + i, you can increment str directly; int length (const char* str) { int i = 0; for (; *str++ != 0; i++) {; return i; } Now in C, a value is false if it is 0, otherwise it is true, so we do not need the != 0, so we can write WebMay 26, 2014 · 7. I am using the code below. char call [64] = {'\0'} /* clean buffer */ strncpy (call, info.called, sizeof (call)); I always use the sizeof for the destination for protecting a overflow, incase source is greater than the destination. This way I can prevent a buffer overflow as it will only copy as much as the destination can handle.
