C Exercises: Check a given array of integers and return true if the given array contains two 5's next to each other, or two 5 separated by one element
C-programming basic algorithm: Exercise-61 with Solution
Write a C program to check a given array of integers and return true if the given array contains two 5's next to each other, or two 5 separated by one element.
C Code:
#include <stdio.h>
#include <stdlib.h>
int main(void){
int arr_size;
int array1[] = {1, 5, 5, 5, 5};
arr_size = sizeof(array1)/sizeof(array1[0]);
printf("%d",test(array1, arr_size));
int array2[] = { 2, 7, 8, 10};
arr_size = sizeof(array2)/sizeof(array2[0]);
printf("\n%d",test(array2, arr_size));
int array3[] = {3, 3, 3, 5, 7, 5};
arr_size = sizeof(array3)/sizeof(array3[0]);
printf("\n%d",test(array3, arr_size));
}
int test(int numbers[], int arr_size)
{
int len = arr_size;
for (int i = 0; i < len - 1; i++)
{
if (numbers[i] ==5 && numbers[i + 1] == 5) return 1;
if (i + 2 < len && numbers[i] == 5 && numbers[i + 2] == 5) return 1;
}
return 0;
}

Previous: Write a C program to check if an array of integers contains a 3 next to a 3 or a 5 next to a 5 or both.
Next: Write a C program to check a given array of integers and return true if there is a 3 with a 5 somewhere later in the given array.

C Programming: Tips of the Day
Static variable inside of a function in C
The scope of variable is where the variable name can be seen. Here, x is visible only inside function foo().
The lifetime of a variable is the period over which it exists. If x were defined without the keyword static, the lifetime would be from the entry into foo() to the return from foo(); so it would be re-initialized to 5 on every call.
The keyword static acts to extend the lifetime of a variable to the lifetime of the programme; e.g. initialization occurs once and once only and then the variable retains its value - whatever it has come to be - over all future calls to foo().
