Swapping of two variables withou using temp variable?
example: x = x-y; y = y-x; x = y-x; <><><> It is not possible to swap two variables without using a temp variable. The code in the answer above, while clever, does not swap the variables. It will exchange the variable values for certain values of x and y, e.g. when x and y are small integers. If x and y are other values, such as strings, pointers, Infinity, NaN (not a number), floating point, or near the limits of the representation (causing over/underflow) then the code will not "swap" the values. <---> Note: there is absolutely no point in swapping two variables without using temopral variable, it's just a typical homework question, already asked here countless times. Another variation: a ^= b; b ^= a; a ^= b;
How do you calculate Total Cost without Total variable cost?
To calculate the Total Cost without Total variable cost, one should estimate for the variables or substitute for the variables with a variable such as X or Y and then solve for the approximate total cost.
What is -15x-3y equals 9?
Since there are two variables in this sum, without knowing what one of the variables is, it is impossible to calculate the other variable.
What is the difference between controlling variables and using controls?
Controlling variables is when you make sure that only one variable is being tested at a time and that there are not other variables that will make your results unclear. Using a control is when you do a trial without the variable to see what the normal results are.
When an experimental shows that one variable makes another variable change and no variables have any affect the experiment shows?
The experiment shows a causal relationship between the two variables, where changes in one variable directly impact the other without interference from any other variables. This suggests a clear cause-and-effect relationship between the variables being studied.
Which research method assesses how well one variable predicts another without specifying a cause and effect relationship between the variables?
Correlational research method assesses the relationship between two variables without implying causation. It examines how changes in one variable are associated with changes in another variable.
What is program in c to swap entered two numbers without using third variable?
The required c program is given below /*Swapping(interchange) the two entered numbers*/ #include<stdio.h> main() { /*Without using third variable*/ int a,b,t; printf("Enter a:"); scanf("%d",&a); printf("Enter b:"); scanf("%d",&b); a=a+b; b=a-b; a=a-b; printf("\n After swapping without using third variable"); printf("\na=%d\nb=%d",a,b); }
When an experiment shows that one variable makes another variable change and no other variables have any effect?
This is known as a direct or causal relationship between the variables. It suggests that changes in one variable directly cause changes in the other variable without the influence of any other factors. The relationship is often described as a cause-and-effect relationship.
When an experiment shows that one variable make another variable change and no other varibles have any effect the experiment shows?
The experiment shows a direct causal relationship between the two variables, indicating that changes in one variable lead to changes in the other. This demonstrates the impact of the manipulated variable on the outcome, without interference from other variables.
How do you write a c program to swap the values of two variables in unix?
#include<stdio.h> void main() { int a=2,b=4; printf("Program for swapping two numbers "); printf("Numbers before swapping"); printf("a=%d and b=%d",a,b); a=((a+b)-(b=a)); printf("Numbers after swapping"); printf("a=%d and b=%d",a,b); getch(); }
Why static variables in a function have global extent?
A variable declared static outside of a function has a scope the of the source file only. It is not a global variable. A variable declared outside of a function and without the static qualifier would be a global variable.
What are the variables for your science project?
There are two types of variables. The first one is called the experimental variable. It is what you are compare everything to or the normal thing. For instance, what plant grows better the one with sunlight or the one without. The one with sunlight would be the experimental variable. The second type of variable is the dependent variable, which is the data you are collecting. Relating back to the plant experiment, how well the plant grows would be the dependent variable.
