I have a string:
char * someString; If I want the first five letters of this string and want to set it to otherString, how would I do it?
562
We can use string function strncpy() to copy part strings. Part of the second string is added to the first string. strcpy(destination_string, source_string, n);
Just add your offset to the str1 argument of the strncpy call. For example: strncpy(str2, str1 + 1, 5); will copy five bytes into str2 from str1 starting at index 1.
The substr() method extracts a part of a string. The substr() method begins at a specified position, and returns a specified number of characters. The substr() method does not change the original string. To extract characters from the end of the string, use a negative start position.
The substring function is used for handling string operations like strcat(), append(), etc. It generates a new string with its value initialized to a copy of a sub-string of this object.
#include <string.h> ... char otherString[6]; // note 6, not 5, there's one there for the null terminator ... strncpy(otherString, someString, 5); otherString[5] = '\0'; // place the null terminator If you love us?
