Program to accept String starting with Capital letter
Given a string str consisting of alphabets, the task is to check whether the given string is starting with a Capital Letter or Not.
Examples:
Input: str = "GeeksforGeeks" Output: Accepted Input: str = "geeksforgeeks" Output: Not Accepted
Approach:
- Find the ASCII value of the first character of the string
- Check if this value lies in the range of [65, 90] or not
- If yes, print Accepted
- Else print Not Accepted
Below is the implementation of the above approach:
C++
// C++ program to accept String // starting with Capital letter #include <iostream> using namespace std; // Function to check if first // character is Capital int checkIfStartsWithCapital(string str) { if (str[0] >= 'A' && str[0] <= 'Z') return 1; else return 0; } // Function to check void check(string str) { if (checkIfStartsWithCapital(str)) cout << "Accepted\n"; else cout << "Not Accepted\n"; } // Driver function int main() { string str = "GeeksforGeeks"; check(str); str = "geeksforgeeks"; check(str); return 0; } |
