C-language operators

I. assignment operator in op= form

int a=0;

A+=1; equivalent to a=a+1;//a*=1;

ii. Expressions of the op= class

int a=10,b=5;

a/=b;//is equivalent to a=a/b;

a*=b+1;//equivalent to a=a* (b+1);

iii. Common mathematical functions

If you do not use these functions, you can skip this content

ABS (X); The absolute value of the integer is X is an integer

Fabs (x);//absolute value of floating-point number x is a floating-point number

sqrt (X);//Open square

Pow (x, y);//xy x and Y are floating-point types
