The last line "scanf_s... The abnormal
""0 x7a9de63c (ucrtbased. DLL) (located in the dome. Exe) caused by abnormal: 0 xc0000005: when writing position 0 x01252000 access conflict,
"

My own practice bracelet:
I speculated that abnormal failure reason is mallco application memory or have no access to memory, but memory should apply validation is successful,,,
Really what's the reason, I didn't learn c + + is a small white, Daniel answer ~ ~ ~

CodePudding user response:

C + +, use the new application memory, the other p1 - & gt; When the name is a string, the scanf don't need & amp; The symbols
Cout & lt;
