Introduction
I have used CodeBlocks compiler for debugging purpose. But you can use any C++ programming language compiler as per your availability.
Write C++ program to change string to lower case without strlwr
#include <iostream>
#include <string.h>
using namespace std;
void functionlower(char []);
int main()
{
char string[100];
cout<<"Enter a string to convert it into lower case: "<<endl;
cin>>string;
functionlower(string); // calling functionlower
cout<<"Entered string in lower case is: "<<string;
return 0;
}
void functionlower(char s[]) {
int c = 0;
while (s[c] != '\0') {
if (s[c] >= 'A' && s[c] <= 'Z') {
s[c] = s[c] + 32;
}
c++;
}
}
Result
