Write a function which takes a C string as an input and converts it to all upper

Question

Write a function which takes a C string as an input and converts it to all uppercase characters. For each lowercase character in the C string, simply subtract 32 from it to form the uppercase character. Any non-alphabetic character in the C string should not be changed. You are not allowed to use any other functions to do this. Do not write a main function. Your function does not do any cin
or cout. Hint: lowercase characters are between 'a' and 'z' where the value of 'z' equals the value of 'a' + 25. Remember, C strings are terminated with the '' character. Make sure to properly format all your code.

Explanation / Answer

string convert(string str)

{

for(int i=0; i<str.length()-1; i++)

{

if(str[i] > 96 && str[i]< 122)

{

str[i] =str[i] - 32;

}

}

return str;

}
