Question

I have a problem as stated below:
i have an array(say) a[]={10,24,56,33,22,11,21}
i have something like this

for(i=0;i<100;i++){
    if(a[i]==10)
        // do something
}

next when i=1

if(a[i]==10 && a[i+1]==24)

so on so at each iteration the arguments / conditions within if should be varying
now this will be a very big sequence i cant explicitly write
if(a[i]==10 && a[i+1]==24 && a[i+2]==56 ...... a[i+100]=2322)

how can i achieve this varying conditions?

Answer 1

You have to have a cumulative “boolean” variable that checks a[i] at the i-th iteration and update that variable:

int a[] = {...};   /* array with some values to verify */
int v[] = {...};   /* these are the actual desired values in a[] */

/* the verifying loop */
int i;
int cond = 1;
for (i = 0; i < 100; i++)
{
    cond = cond && (a[i] == v[i]);
    if (cond)
    {
       /* do something */
    }
}
