Functions in C Problem 1

 Functions in C Problem 1

PROBLEM STATEMENT :

The function/method getProductSign accepts two arguments - SIZE and arr. The integer SIZE represents the size of the integer array arr. 

The function/method getProductSign must return the sign of the product of all the integers in the given array. 

- If the product is a positive value, then the function must return 1. 

- If the product is a negative value, then the function must return -1. 

- If the product is 0, then the function must return 0. 

Your task is to implement the function getProductSign so that the program runs successfully.

Boundary Condition(s): 

1 <= N <= 1000 

-100 <= Each integer value <= 100 

Example Input/Output 1: Input: 4 -1 2 3 -4 Output: 1 Explanation: The product of the given four integers is 24 (-1 * 2 * 3 * -4). Here 24 is a positive value, so 1 is printed. Example Input/Output 2: Input: 5 10 20 -30 4 5 Output: -1 Example Input/Output 3: Input: 3 -6 0 -5 Output: 0

Example Input/Output 1: 
Input: () 
4 
-1 2 3 -4 
Output: 
1 

Explanation: 

The product of the given four integers is 24 (-1 * 2 * 3 * -4). 

Here 24 is a positive value, so 1 is printed. 

Example Input/Output 2: 
Input: () 
5 
10 20 -30 4 5 
Output: 
-1

Example Input/Output 3: 
Input: () 
3 
-6 0 -5 
Output: 
0

SOLUTION :

C (Programming Language)

      
#include <stdio.h> 
#include <stdlib.h> 

int getProductSign(int SIZE, int arr[])
{
    int ind,sign=1;
    for(ind=0;ind<SIZE;++ind) {
        if(arr[ind]==0) return 0;
        else if(arr[ind]<0) sign*= -1;
    }
    return sign;
}

int main() 
{ 
	int N; 
	scanf("%d", &N); 
	int arr[N]; 
	for(int index = 0; index < N; index++) 
	{ 
		scanf("%d", &arr[index]); 
	} 
	printf("%d", getProductSign(N, arr)); 
	return 0; 
}
