C language like a dream-CodePudding

For bosses to see this piece of code which is wrong? Always prompt segmentation fault

CodePudding user response:

Segmentation fault is a cross-border,

Or wild pointer, oh, not a pointer, that this too,

CodePudding user response:

Once said, to avoid mistakes, have to be that we do not over torque,

CodePudding user response:

refer to the second floor forever74 response:

child once said, to avoid mistakes, is that we do not over torque,

Are you a monkey sent to tease than?

, don't put sprout new bosses, help me to look at specific what is wrong? How to change?

CodePudding user response:

Debugging. Look at where the execution time of pop-up error,

CodePudding user response:

reference 4 floor forever74 response:

debugging, see where execution when a pop-up error,

Not debugging
