C Exercises: Check a given array of integers and return true if the specified number of same elements appears at the start and end of the given array
C-programming basic algorithm: Exercise-66 with Solution
Write a C program to check a given array of integers. The program will return true if the specified number of the same elements appears at the start and end of the given array.
C Code:
#include <stdio.h>
#include <stdlib.h>
int main(void){
int arr_size;
int array1[] = {3, 7, 5, 5, 3, 7};
arr_size = sizeof(array1)/sizeof(array1[0]);
printf("%d",test(array1, arr_size, 2));
int array2[] = {3, 7, 5, 5, 3, 7};
arr_size = sizeof(array2)/sizeof(array2[0]);
printf("\n%d",test(array2, arr_size, 3));
int array3[] = {3, 7, 5, 5, 3, 7, 5 };
arr_size = sizeof(array3)/sizeof(array3[0]);
printf("\n%d",test(array3, arr_size, 3));
}
int test(int numbers[], int arr_size, int len)
{
for (int i = 0; i < len; i++)
{
if (numbers[i] != numbers[arr_size - len + i])
{
return 0;
}
}
return 1;
}

Static function in C
Making a function static hides it from other translation units, which helps provide encapsulation.
helper_file.c
intf1(int); /* prototype */ staticintf2(int); /* prototype */ intf1(int foo){ return f2(foo); /* ok, f2 is in the same translation unit */ /* (basically same .c file) as f1 */ } intf2(int foo){ return42 + foo; }
main.c:
intf1(int); /* prototype */ intf2(int); /* prototype */ intmain(void){ f1(10); /* ok, f1 is visible to the linker */ f2(12); /* nope, f2 is not visible to the linker */ return0; }
