1. Write a function which takes a C string as an input and converts it to all up

Question

1. 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. (Points : 20)



2. Write a function which takes one string variable (not C string) as input and modifies the existing string. Try to find "Ohio" or "OHIO" in the input string. If the input string contains either of these, replace those 4 characters with "OH". As an example,
Original string = "Blacklick, Ohio 43004"
Modified string = "Blacklick, OH 43004"
Use an appropriate parameter passing mechanism. Your function will not do any cin or cout. Do not write a main function. Make sure to properly format all your code.

Explanation / Answer

please rate - thanks

void toUpper(char s[])
{int i=0;
while(s[i]!='')
    {if(s[i]>='a'&&s[i]<='z')
        s[i]=s[i]-32;
     i++;
     }    
}

void replaceString(string &in )
{string change[]={"Ohio","OHIO"};
string to="OH";
int i,pos;
for(i=0;i<2;i++)
{pos=in.find(change[i],0);
if(pos !=in.npos)
   {in.erase(pos,change[i].length());
    in.insert(pos,to);
    return;
   }
}
return;
}
