Given a hex string, we have to convert it into an integer using stoi() function. Submitted by IncludeHelp, on March 11, 2019

The results then validates the usage of sprintf! This compare buffer is then used to be validateВ against our swap buffer to give us the results of our test. The reason this buffer is called a reverseBuffer is because this buffer is actually the ASCII value that is built in reverse,В so the for loop underneath the while loop actually then takes the reverseBuffer and builds the compareBuffer. Each iteration isВ added to our reverseBuffer in the while loop and the decimal value is divided lower and lower. The decimal value passed in to the test function is then iterated through with a while loop and the hex characters are generated from the decimal remainder of being divided by 16 with each iteration. From here I created three character buffers, one for the reverseBuffer, that we will use to reverse engineer our decimal value, one for the swapBuffer that we will use to swap our hex data into ASCII, and the last for the compareBuffer to compare the reverse engineered value to our sprintf swap buffer to get the results of our tests.

To test my sprintf code I wrote a loop that took a buffer of unsigned integerВ hexadecimal data and looped through it and sent each value to a testing function as an integer decimal value.

That way if IВ needed this test to be included anywhere else in the project, it would be portable enough andВ could be with one single line of code. To create this test I created a C module using an includable header file. This match would validate that my solution was correct and allow me to continue on with my project with tested code. One way I thought to do this was to manually create an algorithm that converted the decimal form of the hex data into ASCII data so I could then compare the output from sprintf to my hand converted text to see if I had a match. To test my solution of using sprintf, I needed a way to validate that the output I was getting from sprintf was accurate.
