I have to code a program in C that let me sum up a lot of numbers but just every other value of a bigger number, for example, the number 1234, a just have to sum 1 and 3. My question is, how do I access these numbers, is there an easy way to do it??

Depends you could parse the string or if the numbers are similar use mathematical formulas. Can you provide more info?
