Is dev - c + + compiler, transferred to 64 - bit debug mode, operation result is wrong, will pop up a window to debug, debug is down again, can you help me have a look at where went wrong?

CodePudding user response:

This is commonly pointer exception, you step through the breakpoint to the main function to start the first sentence, step by step

CodePudding user response:

Didn't scan your code, but because the data read from the file, save the data and are all fixed. Small array, unless you file content is small or relatively fixed, an array of the risk is too big
