Trim Spaces from a Name — C++ Fundamentals

The context

A sign-up form asks for a name, and people often paste it with stray spaces around it, like " Alice ". If it’s stored as is, searches break, because "Alice " and "Alice" look the same on screen but don’t match.

Your task

Complete the function trim so it meets these requirements:

After the call, the string pointed to by text has no spaces at the start or the end.
Spaces in the middle, like in "Mary Ann", stay.
Use pointer arithmetic instead of indices like text[i].

Expected output

#include <iostream>void trim(char* text) { // TODO: remove spaces from both ends of text}void runCase(char* input) { std::cout << "[" << input << "] -> "; trim(input); std::cout << "[" << input << "]\n";}int main() { // Arrays, not string literals, so the text can be changed char a[] = " Alice"; char b[] = "Bob "; char c[] = " Mary Ann "; char d[] = " "; runCase(a); runCase(b); runCase(c); runCase(d);}
