What is the difference between getch() and getche() in C Language?
The getch() function reads a single character from the keyboard. It doesn’t use any buffer, so entered data will not be displayed on the output screen.
The getche() function reads a single character from the keyword, but data is displayed on the output screen. Press Alt+f5 to see the entered character.
Let’s see a simple example
- #include<stdio.h>
- #include<conio.h>
- int main()
- {
- char ch;
- printf(“Enter a character “);
- ch=getch(); // taking an user input without printing the value.
- printf(“\nvalue of ch is %c”,ch);
- printf(“\nEnter a character again “);
- ch=getche(); // taking an user input and then displaying it on the screen.
- printf(“\nvalue of ch is %c”,ch);
- return 0;
- }
Output:
Enter a character value of ch is a Enter a character again a value of ch is a
In the above example, the value entered through a getch() function is not displayed on the screen while the value entered through a getche() function is displayed on the screen.
