What is the difference between getcher and getch statements in C?

Answer 1

If you are referring to getchar(), it returns a single character as an 'int'.

'scanf' allows the user to input many different types of variables, and converts them accordingly using a format specified by the user.

If you type 'man getchar' and 'man scanf' you will get additional information on how to use them.

Answer 2

/*No of the repetition character in a string */ #include #include void main() { char ch,str[30]; int i=0,count=0; clrscr(); printf("\n\t Enter your name : "); scanf("%s",str); printf("\n\t Enter character : "); ch=getche(); for(i=0;str[i]!='\0';i++) { if(str[i]==ch) count++; } printf("\n\t No of the repetition character %c in a string is %d",ch,count); getch(); }

Answer 3

In the C and C++ runtime library, getc(FILE *stream) reads a single character from a stream and increments the associated file pointer (if there is one) to point to the next character, while getch() reads a single character from the console without echoing it. In the case of getc, getc(stdin) is the same as getchar().

Answer 4

int getchar(void) is the same as getc(stdin) - it returns a single unsigned character (0-255) as an int from the "stdin" stream. It requires the stdio.h library and is therefore available across multiple platforms.

int getch(void) is used with conio.h and curses.h and does something similar. However, if using curses.h, "delay mode" and the setting of "cbreak" determine whether it waits for a character or not plus how it reacts to that situation.

When used from conio.h, it will wait until a character is available and then return it. To detect if a character is available, use the kbhit() function.

Answer 5

Echoing. (Next time you might want to try and use the built-in help system.)
