1, integer array is cleared.

Function: void bjero (void * s, int n)

Header file: # include

Function description: set the first n characters of the string S as 0, generally n takes sizeof(s) to empty the whole space;

2, the array is empty

Usage time: 94 seconds

for(k = 0； k & lt 10000 ; k++)

for(I = 0； I & ltMAXi++)

for(j = 0； j & ltMAXj++)

a[I][j]= 0；
