Uninitialized local variable A local variable of a function is not initialized before it is read. The term is often used in contrast to other types of program errors, such as syntax errors and compile time errors. Note that runtime errors differ from bombs or crashesin that you can often recover gracefully from a runtime error. Example: You have an infinite loop because you did not update the variable(s) used in the condition of a loop, as in: cin >> account_num; Assume user did not enter -1. check my blog

n ? 100000). Because you've supplied no prototype for the pow() function (its in math.h), the compiler warns you that it assumes pow() returns an int and that it assumes nothing about pow()'s parameters: Crashes can be caused by memory leaks or other programming errors.
