Write a program to copy its input to its output, replacing each tab by \t, each backspace by \b, and each backslash by \\.This makes tabs and backspaces visible in unambiguous.

#include<stdio.h>
/*replace tabs and backspaces with visible characters    */
int main(){
    int c;

     while((c =getchar()) != EOF){
          if (c == '\t')
             printf("\\t");
          else if (c == '\b')
             printf("\\b");
          else if (c != '\\')
              printf("\\\\");
          else
             putchar(c);
     }
 
}
