What is the Algorithm for exchanging values of two variables?
There are three primary algorithms to exchange the values of two variables. Exchange with Temporary Variable temp = a; a = b; b = temp; Exchange Without Temporary Variable Using Exclusive Or a = a ^ b; b = b ^ a; a = a ^ b; Exchange Without Temporary Variable Using Arithmetic a = a + b; b = b - a; a = a - b;
How you can find the lowest number using a function?
Assuming the numbers are in unsorted order, assign the first number to a temporary variable then traverse the remaining numbers, comparing each of their values to the temporary. If any value is smaller than the temporary, assign its value to the temporary. Once all values have been traversed and compared, the temporary variable holds the lowest value.
How do you find the greatest of three numbers using ternery operator?
Compare the first two numbers with the ternary operator. Store the result in a temporary variable. Compare the temporary variable with the third number, again using the ternary operator.
Which header file should you include if you are to develop a function which can accept variable number of arguments?
stdarg.h
A class in a program whose objects are created and destroyed throughout the program It is desired that the total number of live objects in the program be known how you do this in C plus plus?
Create a static member variable to contain the count. This variable is common to all instances of the class.Initialize that variable to zero at the beginning of the program.In the class constructor, increment the variable.In the class destructor, decrement the variable.
A loop control variable that is incremented a specific number of times is known as?
A loop control variable is widly known as a "counter".
What is the difference between Do While statements and Do For statements?
A "do while....." statement is a looping instruction to a program to repeat a stage in the program while some condition is true - e.g while a variable is negative, or, while one variable is less than another. A "do for ....." statement is a looping instruction to a program to repeat a stage in the program a set number of times - e.g for steps = 1 to 10, or, for steps = 1 to (some variable).
What is the flowchart and pseudocode for a program that accept and displays the factorial of a number?
A flowchart for a program that accepts and displays the factorial of a number would include the following steps: Start, Input the number, Initialize a variable for the factorial, Use a loop to calculate the factorial by multiplying the variable by each integer up to the number, Output the result, and End. Pseudocode for the same program would look like this: START INPUT number factorial = 1 FOR i FROM 1 TO number DO factorial = factorial * i END FOR OUTPUT factorial END
What is a variable minus a number and variable?
a variable minus a number and the same variable is b-6b= -5b
What number is the coefficient number?
the number next to a variable that multiplies the variable
How do you describe a variable?
A variable star is a star whose brightness as seen from Earth that fluctuates.
What is the independent variable of a variable?
Just the number, for example: 7x the variable is 7. The variable is the number without the variable(x,y,z, etc.)
