How do I refactor my code (in a function) to replace the following nested if-else statements to a do-while loop in C code:

int funciton() { int x; printf("... "); scanf("%d%*c", &x);

if (x < 0) { printf("..."); exit(0);

} else if ((x < 1) || (x > 100)) {

printf("...");

function();

} else {

return x;

}

}
