Thread: Simple Loop Program

3. Write a program that reads a sequence of positive integers and prints out their sum, except that if the
same number occurs several times consecutively, ignore all but the first. Assume an input of 0 marks
the end of the input. For example, if the input is 3 8 5 5 4 9 1 1 1 1 8 0 then you should print 38 (i.e.,
ignore one of the 5's and three of the 1's).

Could anyone help me out with this?

Sorry about that.
here is what I have so far

Code:

#include <stdio.h>
 
int main()
{
int n, sum = 0, c, value;
scanf("%d", &);


for (c = 1; c != 0; c++)
   {
      scanf("%d",&value);
      sum = sum + value;
   }
 
   printf("%d\n",sum);
}

What is 'c' doing? When will c be equal to 0?

Also this won't even compile (line 6)

Code:

#include <stdio.h>

int main()
{
int n, sum = 0, c, value;
scanf("%d", &c);


for (c = 1; c != 0; c++)
   {
      scanf("%d",&value);
      sum = sum + value;
   }

   printf("%d\n",sum);
}

The c variable should be ending the program as soon as 0 is inputted.

Explain, in English, what the following line does.

Code:

for (c = 1; c != 0; c++)
