could anyone tell me why I am getting this output?
for just one case the count value should not be increasing, but I can’t help myself where I am getting wrong, please correct me…
following is my code:
#include <stdio.h>

int main(void) {

int t,n,a[n];

scanf("%d",&t);

while(t--)
{
    scanf("%d",&n);
    
    for(int j=0;j<n;j++)
    {
        scanf("%d",&a[j]);
    }
    
    int count = 1;
    for(int i=0;i<=n;i++)
    {
        if(a[i+1]<=a[i])
        count++;
    }
    
    printf("%d\n",count);
    
    
}
// your code goes here
return 0;

}
