33,200 software development programmer interview questions shared by candidates

Write a function that converts an int into its alpha-numeric equivalent represented as a null terminated string. The function should accept an int as input and return a string as output. For instance, calling the function with an int value of 324 would return a null terminated string containing "324". Ensure that your function checks for appropriate boundary conditions and edge cases. Assume you cannot use any standard libraries (for example, no itoa or sprintf).
