How do I add the negative float numbers only in C? Using only if statements?

Question

The problem goes like this;
1. Ask 4 inputs (float)
2. Only add all inputted negative numbers and print the sum in 2 decimal place.

The code I have tried but get a 6/10 score.

Answer 1

The code is bloated. You could substitute all your if statements for only 4 if-statements.

Here is an example for one of them:

if(num1<0) {
sum += num1;
}

Ipang it sounds like a restriction to not use any loops. Maybe an if-lesson?

Answer 2

Have you learned how to use an array to store multiple inputs? this would've been easier using an array, with a loop and an `if` conditional.

You can also do this using a loop, without array. You just need to set the array to run 4 times, read the input in the loop, and use `if` conditional to add only negative inputs.

Alex,
I don't know for sure, but the scoring 6/10 mentioned made it look less like a lesson quiz ...

Answer 4

Ipang yes its a lesson quiz. I was still wondering how to do it in if statements. since my teacher just skip teaching us about it for switch cases...

Answer 5

Oh okay, in that case, you can follow Alex's suggestion 👍
