Question

Can you write a program to convert a string from uppercase to lowercase and lowercase to uppercase depending on the user's input? In simple C++ please

So for example if the input is Hello then the output should be hELLO

Answer 1

#include <iostream>
#include<string.h>
using namespace std;

void UpperLower(char word[])
{
for(int i=0;i<strlen(word);i++)
{

if(word[i] >= 'A' && word[i] <= 'Z')
{
word[i]=word[i]+32;
}
else
{
word[i]=word[i]-32;
}
}

cout<<word;
}
int main()
{
char word[50];
  
cin>>word;
UpperLower(word);
  
}

output:
