A new MAVEN project has been created today with unhandled event loop exception GC overhead limit exceeded. According to the internet said to increase the maximum heap of memory, the results will be Eclipse.ini parameters to-xmx1024m or error.Finally found on the internet a friend said "do not change eclipse.exe filename ", I went to see the file name has not changed, and the shortcut became "Eclipse.exe-shortcut." I guess it doesn't matter! But took s

struct structure can strengthen the management of variables, increase the readability of the program, but on the other hand, the structure will increase the cost of the program.Look at the following section of code:struct Test_s{int a;int b;float c;}; int _tmain (int argc, _tchar* argv[]) {test_s ts;int a;int b;int c;ts.a = 100;ts.b = 200;TS.C = 300.f;a = 100;b = 200;c = 30 0.f;return 0;}using the Disassembly tool, Assigning 3 variables to a struct, in fact the assembly code under debug is:mov
