? P20 Exercise 1-10

Exercise 1-10. Write a program to copy its input to its output, replacing each tab by \t, eachbackspace by

\b, and each backslash by \\. This makes tabs and backspaces visible in an unambiguous way.

#include <stdio.h>/* replace tabs and backspaces with visible characters */main(){int c;while ((c = getch()) != EOF){if (c == '\t')printf("\\t");else if (c == '\b')printf("\\b");else if (c == '\\')printf("\\\\");else putchar(c);}}
