What are errors in this code segment?

Question

for(p=10;p>0;)
p=p-1;
printf("%f",p);

Answer 1

1. If you want more than one statement of code to run in the for loop (or any loop, if, else etc) you need to enclose the code between curly braces { and }.
2. It looks like you're trying to print out an integer using %f which is meant for a float. Use %d instead.

You could also just add your decrementing as the last statement in the parentheses.

#include <stdio.h>

int main() {
int p;
for(p = 10; p > 0; p--) {
printf("%d\n", p);
}
return 0;
}

Answer 2

for (int p = 10; p < 0;)
p -= 1;
printf(“%d”, p);

The first problem is that you didn’t declare p, unless that was earlier in the program.

The second line works fine, but I replaced it because it is easier to write it this way and does the same thing.

For the third line, %f is for float or double, not int which I assumed p was. %d is for int.
