maximum unsigned int

Just like int A, int can also be decorated with other modifiers. In addition to the void type, the base data type can be preceded by a variety of type modifiers, such as the following four types of modifiers:1.signed----Signed, can be decorated with

1 int i=3; 2 cout1;ask what the result is. First reaction:-3. But the result does not seem like this, wrote a program, ran a bit, found that:4294967293. 1) on a 32-bit machine, the int and unsigned int are 32 bits (4 bytes). 2) enum will be

In the 32-bit environment, use C to design a 32-bit unsigned long integer summation function that is stored in two 32-bit unsigned integers. function interface is defined as void Add64 (unsigned int add1, unsigned int add2, unsigned int* psumhigh,
