In this post, we will write a C++ program to convert the small case letters to upper case letters with practical program code examples and complete a full explanation with output.
C++ program to convert the small case letters to upper case letters
#include<iostream>
#include<conio.h>
#include<string.h>
#include<windows.h>
BOOL gotoxy(const WORD x, const WORD y) {
COORD xy;
xy.X = x;
xy.Y = y;
return SetConsoleCursorPosition(GetStdHandle(STD_OUTPUT_HANDLE), xy);
}
int main()
{
system("cls");
char ch;
char arr[5];
int i=1,j=1,c=1;
arr[i] = getch();
while(arr[i] != 27)
{
gotoxy(j,c);
std::cout<<arr[i];
i++;
arr[i] = arr[i-1];
int k = arr[i]-32;
i--;
arr[i] = getch();
gotoxy(j,c);
std::cout<<char(k);
j++;
if(j==80)
{
j = 1;
c = c+1;
}
}
return 0;
}
Output
THIS IS THE EXAMPLE
