C programming Question Help1
Write a simplified version of printf in which the two conversion specifications are %d and %s. Each %d in the the format string indicates an int argument and each %s indicates a char* (string) argument. If the function encounters a % character thatís not immediately followed by a d or s character, it should ignore both characters. The function should use calls of putchar to produce all output. You may assume that the format string doesnít contain escape sequences. Test your function with a C program

For extra credit, when given the source your routine should verify the arguments passed match the format string. Yes, printf is variadic. Your version should be so as well.
Post again if you run into specific trouble with your algorithm or program. It's best if you post
)A minimal amount of code that exhibits the problem;
)Input that caused the trouble if you make it as far as runtime;
)Output you expected. That's critical. Would you believe that many of the posts here don't include "why it's a problem" information? In this case the problem appears well defined. Good start.

[/code] are essential for python code and Makefiles!

Pretty sure nobody here is going to do your homework for you. At least that's the way it should be. Have you got a specific question to ask?
