You can complete the assignment by following the instructions in the following code:

Charles? c[4]；

int？ I = 100；

*(int*)c？ =? Me; Memcpy can also be used, and the schematic code is as follows:

memcpy(c & amp； I，sizeof(I))； The first method is recommended, so when you want to return a value, you just need to follow the following operation.

Me? =? *(int *)c； Flexible use of pointer type conversion can greatly simplify the program code, and this problem is a good example.
