Here, we will create an array of integers then we will find the missing number from the array.
Program:
The source code to find the missing number in the array is given below. The given program is compiled and executed using GCC compile on UBUNTU 18.04 OS successfully.
// C program to find the missing number in the array
#include <stdio.h>
int main()
{
int arr[] = { 1, 2, 3, 5, 6 };
int size = 0;
int i = 0;
int missing = 0;
size = sizeof(arr) / sizeof(arr[0]);
missing = (size + 1) * (size + 2) / 2;
for (i = 0; i < size; i++)
missing = missing - arr[i];
printf("Missing number is: %d\n", missing);
return 0;
}
Output:
Missing number is: 4
Explanation:
Here, we created an array arr with 5 elements. And, we also created three variables size, missing, i that are initialized with 0. Then we found missing elements from the array and printed the result on the console screen.
