I have a struct with an array of 100 int (b) and a variable of type int (a)

I have a function that checks if the value of "a" is in the array and i have generated the array elements and the variable with random values.

but it doesn't work can someone help me fix it?

#include <stdio.h>
#include <stdlib.h>
#include <time.h>

typedef struct {
    int a;
    int b[100];
} h;

int func(h v){
    int i;

    for (i=0;i<100;i++){
        if(v.b[i]==v.a) 
            return 1;
        else 
            return 0;
    }

}

int main(int argc, char** argv)
{
    h str;
    srand(time(0)); 
    int i;
    for(i=0;0<100;i++){
        str.b[i]=(rand() % 10) + 1;
    }
    str.a=(rand() % 10) + 1;
    str.a=1;

    printf("%d\n",func(str));

    return 0;
}
