We’ve been given an array A[N] of N numbers of element. We need to find the product of it’s element.
Like we have an array arr[9] of 9 elements so its product will be like
Product=8,977,500,000,000
Example
Input: arr[] = { 10, 20, 3, 4, 8 }
Output: 19200
Explanation: 10 x 20 x 3 x 4 x 8 = 19200
Input: arr[] = { 1, 2, 3, 4, 3, 2, 1 }
Output: 144
Steps for solving this problem
- Take an input for the size of array
- Take an array as input
- Iterate the array and multiply each element of the array
- Print the result
Algorithm
Start
In function int prod_mat(int arr[], int n)
Step 1-> Declare and initialize result = 1
Step 2-> Loop for i = 0 and i < n and i++ result = result * arr[i]; Step 3-> Return result
int main()
Step 1-> Declare an array arr[]step 2-> Declare a variable for size of array
Step 3-> Print the result
Example
#include<stdio.h>
int main()
{
int N;
scanf("%d",&N);
long answer=1;
int A[N];
for(int i=0;i<N;i++)
{
scanf("%d",&A[i]);
}
for(int i=N-1;i>0;i--)
{
answer=(answer*A[i]);
}
printf("%ld",answer);
}
Input
9
1 200 50 70 30 15 10 19 150
Output
If run the above code it will generate the following output −
8,977,500,000,000
