Search element from user define array

#include<stdio.h>
int main()
{
int a,i,found=0;
 int array[10]={1,2,3,4,5,6,7,88,9,0};
printf("\nenter the array element which want to search");
scanf("%d",&a);
for(i=0;i<9;i++){
if(array[i]==a)
{
printf("element is present");
found=1;
break;


}
}

if(found==1){
printf("\nelement is present at index %d",i);
}
else{
printf("\n element is not present");
}

}
===================================================================
enter the array element which want to search5
element is present
