Print First uppercase letter in a string c++

In this example, we will see a C++ program through which we can find and print the first uppercase character of a given string.

Program:

#include <bits/stdc++.h>
using namespace std;
//function to return first uppercase
//character from given string
char getFirstUppercaseCharacter(string str)
{
//loop that will check uppercase character
//from index 0 to str.length()
for(int i=0; i<str.length(); i++)
{
//'isupper() function returns true
//if given character is in uppercase
if(isupper(str[i]))
return str[i];
}
return 0;	
}
//Main function
int main()
{
//defining two strings
string str1 = "asjhdaksdak";
string str2 = "jsadh Jerry kas uash";
//first string check 
cout<<"Given string: "<<str1<<endl;
char chr = getFirstUppercaseCharacter(str1);
if(chr)
cout<<"First uppercase character is: "<<chr<<endl;
else
cout<<"No uppercase character found in string"<<endl;
cout<<endl;
//second string check 
cout<<"Given string: "<<str1<<endl;
chr = getFirstUppercaseCharacter(str2);
if(chr)
cout<<"First uppercase character is: "<<chr<<endl;
else
cout<<"No uppercase character found in string"<<endl;	
return 0;
}

Output:
Given string: asjhdaksdak
No uppercase character found in string
Given string: asjhdaksdak
First uppercase character is: J
