Operations in the C language

C language has the The subtraction operator, including common operations such as the

take the remainder operation % : The value of the positive and negative values of the result of taking the remainder % the value of the left number is about

Arithmetic operations:

/*

Prompt for the number of seconds to enter a time, such as a few seconds to input , and then output the corresponding minutes and seconds, such as seconds is 8 points - seconds

*/

#include <stdio.h>

Int Main ()

{

       // define a variable to accept the input value

Int time;

       // Print Tips

Printf (" Please enter a time value of %d seconds ");

       // receive a data

SCANF ("%d", &time);

       // Convert seconds

int minute = TIME/60;

int second = time%60;

printf ("%d minutes %d seconds ", minute,second);

return 0;

}

Assignment operation:

Compound assignment operators: a +=5+10 ;

Self-increment/decrement:

int b,a=10;

b = (a++) + (++a);

printf ("a=%d,b=%d", A, b);

sizeof

Used to calculate the number of bytes of memory for a variable, a constant, or a data type

Relational operations

1. Conditional Judgment

2. true or false: any non- 0 The values are true, only 0 It 's a fake .

3. Relationship Comparison:>,<,==,! =,>=,<=Established as"really",Otherwise, the"Fake"

the precedence of relational operators is: left-to-right < , > , <= , >= , == , !=

The precedence of a relational operator is less than the precedence of an arithmetic operator

Logical operation:

1.&& Logic and

2.| | Logical OR

3.! Logical non-

Trinocular operator

int a=10>5?9:89

condition to be established return 9 condition not established return the

Calculates the maximum value of three numbers

#include <stido.h>

int main ()

{

int a=90,b=80,c=100,d;

int d= (A>B?A:B)? C: (A>B?A:B): C;

printf (" the largest of these three numbers is:%d", d);

return 0;

}
