If your answer is two digits long (for instance, 28), carry the first digit of your answer (e.g., 2) above the digit in the tenths place of the top number. printf("%c", 'abcd'). This compiles and runs fine and the multi-character literal stores as an integer value (from where the number comes you will find below). Never knew of the putchar function before now, Thanks! For this ASCII value is used. Then calculate the sum of the alphabetical values of the given string. Then the str is "gggggggg". @Barmar I am not saying it's useful. No shortcuts. In order to represent characters, the computer has to map each integer with a corresponding character using a numerical code. Multiplying a char array by a number is defined, but it will not do what you're trying to do. What is the purpose of a function prototype?

What are some compounds that do fluorescence but not phosphorescence, phosphorescence but not fluorescence, and do both? Sorry, C is a low-level system language. [The notation "16x16" means a 16-bit multiply. And assuming a reasonable mapping, you'll likely see "ABCD" or "EFGH" in the object code. (This isn't guaranteed by the language; the implementation must document the mapping, but it needn't be reasonable.) Darn..I guess for loop is the way to go. Moreover, since you cannot define ( or overload ) operators in c, there is no standard-compatible way to achieve it. Replace a column/row of a matrix under a condition by a random number. The multiplicative operators perform multiplication (*), division (/), and remainder (%) operations. You have to do all that yourself: allocate a character array, copy characters into it with a loop, even add the null terminator at the end. I never knew there was a cheat like this. As pedantic compiler flag generally passed it gives a warning on all multi-character literals. Using robocopy on windows led to infinite subfolder duplication via a stray shortcut file.
