i want the sum of all integers number up to 100 and i want it full C formelar

Question

i want it full formelar #include etc...

Answer 1

The sum is 100*101/2=5050. I cannot give you the C coding but the formula is n(n+1)/2 where n=100 in this case.

Coding is of the form:

function nsum (int n)

int i;

i = n * n + n;

i = i / 2;

return i;

end function

print nsum(100);
