isupper() function is to be used.

#include<iostream.h>
#include<ctype.h>  // for the isupper() function

void main()

         int count=0;
         char string[10];

Answer 2

string = input("Enter a string: ")

ccap = 0

for i in string:

 if i.isupper():

   ccap = ccap + 1

print("There are ", ccap, "upper case letters.")

isupper() is a string function that checks if a character is upper case or not.

Other similar functions:

• islower() - checks if a character is lower case or not.
• upper() - converts all characters into upper case.
• lower() - converts all characters into lower case.
• capitalize() - converts the first character in the string into upper case.
