Write a program in C that will sum all the numbers from 1 to 1000 while ignoring all numbers divisible by 10 and 5

Following are the code

#include / /header file

int main () / / main function

{

int sum=0; / / variable declaration

for (int i=1; i<=1000; i++) / / iterating over the loop

{

if (i%10!=0 && i%5!=0) / / check the condition & ignoring all numbers divisible by 10 and 5

sum=sum+i; / / calculate sum

}

printf ("%d", sum); / / print sum

return 0;

}

Explanation:

In this program we initialized an "sum " variable with "0", iterating over the loop and ignoring all numbers divisible by 10 and 5 and finally calculate sum.

output

400000
