Differentiate c constant and c variables?
Differentiate between constants and variableConstantsvariablescharacteristicsValue is not changeableduring the course of the programValue can be changedanytime during the course of the programusageUse constant when you want to declare something that won't change midway in your program execution.Use variable to store data thatmay or will change during the running of the program.
What is the meaning of identifiers in c language?
The NAMES that identify or represent the variables, constants, data types, functions and labels in C language.. They are mere(only) NAMES, that help in IDENTIFYING variables, data types, constants, functions and labels to differentiate them from each other.. A good identifier must be descriptive but short..
What is meant by pointers in c language?
Variables (or constants) that contain addresses.
What is standard form in a linear equation?

When can you say that the equation is linear?
An equation is linear when it contains only variables of degree 1 and constants. ALL linear equations will be of the form: a1x1+a2x2+a3x3+...+anxn=c where an and c are constants.
What are 5 forms of equations of lines?
Standard form: ax + by + c = 0 (a, b, c constants, x and y variables)Slope intercept form: y = mx + c (m, c constants, x and y variables)Two points form: given P = (a, b) and Q = (c, d)(y - b)*(x - a) = (d - b)*(c - a ) (a, b, c, d constants, x and y variables)Parametric equation x = a + r*cos(t), y = b + r*sin(t) (a, b, t constants, x and y variables)X = A + k*B (X, A and B vectors, k scalar, X and k variables).The standard form, parametric equation and vector form have simple analogies for 3 or more dimensions.
What is the general form of linear equation in two variable?
ax + by + c = 0 where x and y are the variables, a, b and c are numerical constants.
What is a straight line graph?
It is the graphical representation of a linear relationship between two variables. In its most general form, the relationship is of the form a1x1 + a2x2 + ... + anxn + c = 0 where x1, x2 etc are variables, and the as are constants. This equation would be a straight line in n-dimensional space. In 2-dimensional space, and renaming the variables, you get ax + by + c = 0 where x and y are the variables and a, b and c are constants. This equation can be expressed in the form y = mx + d where m and d are constants. m is called the slope or gradient. For every increase of 1 unit in x, you will get an increase of m units in y. Also, d is called the intercept and it represents the value of y when x is 0.
Coding constants in c?
Coding constants in c means writing the constants in a certain way that the c language understands.
What type of equation results into a straight line graph?
A linear equation! The general form, in n-dimensional space, is a1x1 + a2x2 + ...+ anxn = c where the ai and c are constants and the xi are variables.
What is the science equation from a straight line graph?
ax + by + cz + ... = k where x, y, z, etc are variables and a, b, c etc and k are constants. In the simple case of 2 variables, this becomes ax + by = k which can be rewritten as y = mx + c (different c from the first equation above).
