Hey.

The task. Translate inches to cm. I enter 2i, should bring 5.08 cm.

#include <stdio.h> int main() { int x; char ch; ch = getchar(); scanf("%d%c", &x, &ch); //ch = getchar(); if (x == 2 && ch == 'i') printf("%lf cm\n", 2.54 * x); //2i = 5.08cm }

Where is the mistake? I may not understand something, the check seems to be worth it.

  • Slightly clarify the wording of the answer @dzhioev. The result of getchar () was overwritten in the variable ch 'i', which was entered into scanf (). If you entered 2ii then everything would work. - avp

Why do you call getchar? After all, it reads the first character from the input, so the next you get is not what you expected.

    removed the getchar () function. Why did I use it?) So it was char ch)) thanks for the answer) - marioxxx
