It's the modulo operator which returns the remainder of the left side divided by the right side. Let's suppose a example. If we devide 5/2. Then. 5%2 will evalutate to 1.


What does %= mean in C?

%= Modulus AND assignment operator. It takes modulus using two operands and assigns the result to the left operand. C %= A is equivalent to C = C % A.

What is %% in C programming?

What does the modulus operator '%' do in C++?

What is %LF in C?

For type long double, the correct format specifier is %Lf. For input using the scanf family of functions, the floating-point format specifiers are %f, %lf, and %Lf. These require pointers to objects of type float, double, and long double, respectively.

When to use %d in C?

C
  1. %d takes integer value as signed decimal integer i.e. it takes negative values along with positive values but values should be in decimal otherwise it will print garbage value. ...
  2. %i takes integer value as integer value with decimal, hexadecimal or octal type.


What is the use of the '%' operator?

The remainder ( % ) operator returns the remainder left over when one operand is divided by a second operand. It always takes the sign of the dividend.


How to convert negative value to positive in C?

a = -0.340515; to convert this into positive number I used the abs() method as: a = abs(a);

How to print modulus in C?

  2. using namespace std;
  3. int main(void)
  4. {
  5. int a, b;
  6. int res; // store the result of modulus expression.
  7. a = -5;
  8. b = 2;


What is %5d in C program?

Example: "%5d" will be "..123" after processing (periods mean blanks) - number 0 at the beginning of the first string of digits specifies inserting digits 0 instead of the blank. Example: "%05d" will be "00123" after processing.


Why use %s in C?

%s means a string character, while %d means a signed decimal integer. Every format specifier is there for a reason and the reason for %s is that it's used if the user has to enter a string of characters, while %d is used to specify the signed decimal integer.

What does %= mean in Java?

%= The percentage and equal symbol together is a shorthand for a modulo assignment. That is to say, this symbol combination means a variable is equal to its current value plus the remainder of the current value divided by a new value.

What does the percent mean in C?

Everyone knows that, at least in C, you use the printf family of functions to print a formatted string. And these functions use a percent sign ( % ) to indicate the beginning of a format specifier. For example, %d means to print an int , and %u means to print an unsigned int .

How to ignore negative values in C?

How to ignore negative values in array in C
  1. when you find a negative loop restart the body of the loop if (a[i] < 0) { printf(... ...
  2. Instead of if (a[i] > 0) use else . ...
  3. BTW: Using scanf for user input is problematic. ...
  4. "Whole numbers only, Try again\n" does not match code a[i] < 0 .


Can we store negative value in C?

The C standard doesn't mandate any particular way of representing negative signed numbers. In most implementations that you are likely to encounter, negative signed integers are stored in what is called two's complement. The other major way of storing negative signed numbers is called one's complement.


How do you turn a negative into a positive?

All you have to do is just multiply a negative value with -1 and it will return the positive number instead of the negative. Below you have a range of cells with negative numbers. So to convert them into positive you just need to enter the formula in cell B2 and drag it up to the last cell.

Is %f for float or double?

Both the %f format specifier and the %lf format specifier represent float and double. The printf() in c treats both float and double the same. Note : In the case of a general specifier (e.g. int) the value will be type cast and the integer value will be printed.

How to use %C in C?

printf("I like %c%s", 'C', " very much!"); %c Character %s String of characters To print an individual character, use %c. This causes its matching argument to be output, unmodified, to the screen. To print a string, use %s.

How to print %D in C++?

In this program, we have used the printf() function to print the integer num and the C-string my_name . printf("num = %d \n", num); printf("My name is %s", my_name); Here, %d is replaced by the num variable in the output.


What does %= mean?

It's a Modulo operation which is the same as taking the remainder from division. minutes%=60; is the same as minutes = minutes % 60; which is the same as minutes = minutes - (((int) (minutes/60)) * 60);
