Test. MChar [0]='E'; 

Char t=static_cast & lt; char> (test. MInt); 

Printf (" % % % % c, c, c, c/n ", the test. The mChar [3], the test. The mChar [2], the test. The mChar [1], the test. The mChar [0]). 
Printf (" % % % % c, c, c, c/n ", (test. MInt> 24) % 256, (test. MInt> 16) % 256, (test. MInt> 8) % 256, test. MInt % 256);
