Write a program to copy its input to its output, replacing each backspace by \b, and each backslash by \\.

#include

int main()
{
int c, d;

while ( (c=getchar()) != EOF) {
d = 0;
putchar('d');
//putchar((int)c);
if (c == '\\') {
putchar('\\');
// putchar('\\');
d = 1;
}
if (c == '\t') {
putchar('\t');
// putchar('t');
d = 1;
}
if (c == '\b') {
putchar('\b');
// putchar('b');
d = 1;
}
if (d == 0)
putchar(c);
}
return 0;
