C Exercises: Check if a triple is presents in an array of integers or not
C-programming basic algorithm: Exercise-16 with Solution
Write a C program to check if a triple is presents in an array of integers or not. If a value appears three times in a row in an array it is called a triple.
C Code:
#include <stdio.h>
#include <stdlib.h>
int main(void){
int arr_size;
int array1[] = {1, 1, 2, 2, 1};
arr_size = sizeof(array1)/sizeof(array1[0]);
printf("%d",test(array1, arr_size));
int array2[] = {1, 1, 2, 1, 2, 3};
arr_size = sizeof(array2)/sizeof(array2[0]);
printf("\n%d",test(array2, arr_size));
int array3[] = {1, 1, 1, 2, 2, 2, 1 };
arr_size = sizeof(array3)/sizeof(array3[0]);
printf("\n%d",test(array3, arr_size));
}
int test(int nums[], int arr_size)
{
for (int i = 0; i < arr_size - 1; i++)
{
if(nums[i] == nums[i + 1] && nums[i + 2] == nums[i])
return 1;
}
return 0;
}
Sample Output:
0 0 1

Previous: Write a C program to count the number of two 5's are next to each other in an array of integers. Also count the situation where the second 5 is actually a 6.
Next: Write a C program to compute the sum of the two given integers. If the sum is in the range 10..20 inclusive return 30.

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().
