C Exercises: Check two given arrays of integers of length 1 or more and return true if they have the same first element or they have the same last element
C-programming basic algorithm: Exercise-35 with Solution
Write a C program to check two given arrays of integers of length 1 or more and return true if they have the same first element or they have the same last element.
C Code:
#include <stdio.h>
#include <stdlib.h>
int main(void){
int array11[] = {10, 20, 40, 50};
int arr_size11 = sizeof(array11)/sizeof(array11[0]);
int array12[] = {10, 20, 40, 50};
int arr_size12 = sizeof(array12)/sizeof(array12[0]);
printf("%d",test(array11,array12,arr_size11,arr_size12));
int array21[] = {10, 20, 40, 50};
int arr_size21 = sizeof(array21)/sizeof(array21[0]);
int array22[] = {11, 20, 40, 51};
int arr_size22 = sizeof(array22)/sizeof(array22[0]);
printf("\n%d",test(array21,array22,arr_size21,arr_size22));
}
int test(int nums1[], int nums2[], int arr_size1, int arr_size2)
{
return nums1[0] == nums2[0] || nums1[arr_size1 - 1] == nums2[arr_size2 - 1];
}

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().
