This is the second problem from Project Euler. here the detail:

Each new term in the Fibonacci sequence is generated by adding the previous two terms. By starting with 1 and 2, the first 10 terms will be:1, 2, 3, 5, 8, 13, 21, 34, 55, 89, ...

By considering the terms in the Fibonacci sequence whose values do not exceed four million, find the sum of the even-valued terms.

and here is my code in C:

Compiling run without error, however when i run the program(.exe file) from command prompt, it do nothing. I dont know what to do next, since there is no error statement to look at.Code:#include <stdio.h> int main() { int sum = 0, a = 1, b = 2, c=0; while(b<4000000) { c=a+b; if ( c%2==0 ) { continue; if (c<4000000) { sum=sum+c; } } a = b; b = c; } sum=sum+1; printf ("%d", sum); return 0; }
