array

[SpEkTrE]

I am reading in an array and then need to do some simple steps.




what is the code used to calculate the sum of the first 5 integers?


Then the last five integers?

Then of course all the integers?

thanks

int num_array[] = {6,12,97,45,26,1,91,85,74,35,64,59,10,19,98,9,29,23};

int i;
for(i=0, sum=0; i<5; i++) {
   sum+=num_array[i];
}

for(i=0, sum=0; i<5; i++) {
   sum+=num_array[sizeof(num_array)/sizeof(num_array[0]) - i - 1];
}

for(i=0, sum=0; i < sizeof(num_array)/sizeof(num_array[0]); i++) {
   sum+=num_array[i];
}
