The string itself, its size. Answer (1 of 6): Assuming you use zero-based indexing, where the first character in the string is at position 0, you'd read in the desired index, make sure it isn't out-of-range, and then use the index to get the desired character value, ie: [code]#include <stdio.h> #include <string.h> int main. Similarly, we can use the built-in front() function in C++ to get the first character of a string. c++ string index access. String find is used to find the first occurrence of sub-string in the specified string being called upon.
