Question

In a school exercise (on paper) i’ve this question:

5) rewrite the code without using continue and break:

for (i = 0; i < N; i++) {
    scanf("give me an int %d", & a);
    if (a < 0) {
        continue;
    }
    if (a == 0) {
        break;
    }
    /* elaborate positive int */
}

---

I’m thinking about this:

for(i=0;i<N;i++){

 scanf("give me an int %d",&a");

 if(a==0){return -1; //??i dont know how to exit}
 if(a<0){
  do{
        scanf("give me an int %d",&a");
        if(a==0){return -1; //??i dont know how to exit}
    }while(!(a<0))
 }
 /* elaborate positive int */
}

but, I’m actually not able to do this.. can you help me? thanks 🙂

Answer 1

for(i = 0; i < N && a != 0; i++)
{
    scanf("give me an int %d",&a");
    if(a>0)
    { /*do stuff*/ }
}
if(a==0) i--; //As noted by Daniel Fischer
