Information: If you need to know the entire system information can also be obtained from the/proc/stat, including CPU usage, disk space, memory swap, interrupt and so on.? CPU information: Use the/proc/cpuinfo file to obtain the current accurate information of the CPU.Load information: The/proc/loadavg file contains system payload information.? System memory Information: The/proc/meminfo file contains details about the system memory, which shows the amount of physical memory, the number of free

. such as (int *) malloc (the number of sizeof (int) * elements);Code:voidM_alloc () {//dynamically request 20 bytes of memory space, the first address of the memory space is placed in P int*p = (int*) malloc (5*sizeof(int)); //determine if the assignment was successful if(p!=NULL) {memset (void*) P,0,sizeof(p)); for(intI=0; i5; i++) {printf ("%d\t", *p++); } printf ("\ n"); //if it succeeds, the data can be stored.*p =1; * (p+1) =Ten; * (p+2)

the difference between = = and the Equals method and the application of Integer and string = = compares the address memory addresses of two objects, while equals compares the values of two objects.For example, the Equals comparison method of string, first call = = to determine whether the same, and then determine whether the object value is the same char array. integer and int = = Operations the integer and int = = are judged primarily by the address. Example below int i = m; Integer i1 = m; S
