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++
#include <iostream>
using namespace std;
int checkIfStartsWithCapital(string str)
{
if (str[0] >= 'A' && str[0] <= 'Z' )
return 1;
else
return 0;
}
void check(string str)
{
if (checkIfStartsWithCapital(str))
cout << "Accepted\n" ;
else
cout << "Not Accepted\n" ;
}
int main()
{
string str = "GeeksforGeeks" ;
check(str);
str = "geeksforgeeks" ;
check(str);
return 0;
}

Java
class GFG {
static int checkIfStartsWithCapital(String str)
{
if (str.charAt( 0 ) >= 'A' && str.charAt( 0 ) <= 'Z' )
return 1 ;
else
return 0 ;
}
static void check(String str)
{
if (checkIfStartsWithCapital(str) == 1 )
System.out.println( "Accepted" );
else
System.out.println( "Not Accepted" );
}
public static void main(String[] args)
{
String str = "GeeksforGeeks" ;
check(str);
str = "geeksforgeeks" ;
check(str);
}
}

Python3
def checkIfStartsWithCapital(string):
if (string[ 0 ] > = 'A' and string[ 0 ] < = 'Z' ):
return 1
else :
return 0
def check(string):
if (checkIfStartsWithCapital(string)):
print ( "Accepted" )
else :
print ( "Not Accepted" )
if __name__ = = "__main__" :
string = "GeeksforGeeks"
check(string)
string = "geeksforgeeks"
check(string)

C#
using System;
class GFG {
static int checkIfStartsWithCapital( string str)
{
if (str[0] >= 'A' && str[0] <= 'Z' )
return 1;
else
return 0;
}
static void check( string str)
{
if (checkIfStartsWithCapital(str) == 1)
Console.WriteLine( "Accepted" );
else
Console.WriteLine( "Not Accepted" );
}
public static void Main()
{
string str = "GeeksforGeeks" ;
check(str);
str = "geeksforgeeks" ;
check(str);
}
}

Javascript
<script>
function checkIfStartsWithCapital(str)
{
if (str[0] >= 'A' && str[0] <= 'Z' )
return 1;
else
return 0;
}
function check(str)
{
if (checkIfStartsWithCapital(str))
document.write( "Accepted<br>" );
else
document.write( "Not Accepted<br>" );
}
var str = "GeeksforGeeks" ;
check(str);
str= "geeksforgeeks" ;
check(str);
</script>

Output:
Accepted
Not Accepted
Time complexity: O(1)
Auxiliary space: O(1)
