In this example, You learn about C++ program for convert string to lower case and upper case.
Here you learn convert string to lower case and upper case in C++, You are given a string and the task of the program to find convert string to lower case and upper case.
C++ Program for Convert String to Lower Case and Upper Case
#include <iostream>
using namespace std;
void lowerString(string str)
{
for(int i=0;str[i]!='\0';i++)
{
if (str[i] >= 'A' && str[i] <= 'Z') //checking for uppercase characters
str[i] = str[i] + 32; //converting uppercase to lowercase
}
cout<<"\n The String in Lower Case: "<< str;
}
void upperString(string str)
{
for(int i=0;str[i]!='\0';i++)
{
if (str[i] >= 'a' && str[i] <= 'z') //checking for lowercase characters
str[i] = str[i] - 32; //converting lowercase to uppercase
}
cout<<"\n The String in Upper Case: "<< str;
}
int main()
{
string str;
cout<<"Enter the String: ";
getline(cin,str);
lowerString(str); //function call for convert string to lowercase
upperString(str); //function call for convert string to uppercase
return 0;
}
OutputEnter the String: CoDEamY The String in Lower Case: codeamy The String in Upper Case: CODEAMY
