Why clrscr is used after variable declaration?
What is wrong with this code such that it doesnt produce the input reversed? #include <stdio.h> #include <stdlib.h> #include <string.h> int main(void) { char Space = ' '; char LineOfText; float count; LineOfText = getchar(); while ((LineOfText = getchar()) != '/n'); { count = strlen(LineOfText) - 1; while (count >= 0) { putchar(LineOfText[count]); count--; } } getchar(); return 0; }
#include<stdio.h> void main() { int a=10,b=20,c=30; printf("%d",scanf("%d%d%d",&a,&b,&c)); } what is the output for this?

if a is an integer variable, a=5/2; will return a value a) 2.5 b) 3 c) 2 d) 0
