What is exit() function in C language?
The exit () function is used to break out of a loop. This function causes an immediate termination of the entire program done by the operation system.The general form of the exit() function is as follows −void exit (int code);The value of the code is returned to the calling process, which is done by an operation system. Generally, zero is used as return code to indicate normal program termination.ExampleFollowing is the C program for use of exit() function −#include void main(){ char ch; printf("B: Breakfast"); printf("L: Lunch"); printf("D: Dinner"); printf("E: Exit"); printf("Enter your choice:"); ...
Read MoreC program to print four powers of numbers 1 to 9 using nested for loop
Nested loops consist of one loop placed inside another loop.An example of a nested for loop is as follows −for (initialization; condition; operation){ for (initialization; condition; operation){ statement; } statement; }In this example, the inner loop runs through its full range of iterations for each single iteration of the outer loop.ExampleFollowing is the C program to print the table of first four powers of numbers 1 to 9 by using nested for loop − Live Demo#include void main(){ int i, j, k, temp, I=1; printf("I\tI^2\tI^3\tI^4 "); printf("--------------------------------"); for ( i ...
Read MoreWhat are printf conversion characters and their types?
The use of printf is to print out a string with no blank fields to be filled.For example, printf ("An ordinary string.."); printf ("Testing 1, 2, 3...");The next simplest case that has been used before now is to print out a single integer number.int number = 48; printf ("%d", number);The two can be combined as shown below −int number = 48; printf ("Some number = %d", number);The result of this last example is to print out the following on the screen −Some number = 48Here is a list of the different letters for printf −d − signed denary integeru − ...
Read MoreC program to convert decimal fraction to binary fraction
Consider the examples given below to understand how to convert a decimal fraction to binary fraction in C programming language.Example 1 − Conversions of 25 to binary.Step 1 − 25 / 2 Rem : 1 , Quo : 12Step 2 − 12 / 2 Rem : 0 , Quo : 6Step 3 − 6 / 2 Rem : 0 , Quo: 3Step 4 − 3 / 2 Rem : 1 , Quo: 1Step 5 − 1 / 2 Rem : 1 , Quo: 0So equivalent binary number is: 11001Example 2 − Conversions of 0.7 to binary.Step 1 − 0.7 * ...
Read MoreC program to compute the polynomial regression algorithm
Regression is a predictive modelling technique that investigates the relationship between a dependent and non-dependent variable.Polynomial regressionIt is a form of regression analysis that shows the relationship between an independent variable x and the dependent variable y that is modelled a nth degree polynomial in x.ExampleFollowing is the C program to compute the polynomial regression algorithm −#include #include #include main(){ int i,j,k,m,n; float x[20],y[20],u,a[10],c[20][20],power,r; printf("enter m,n:"); scanf("%d%d",&m,&n); for(i=1;i

Read MoreC program to compute linear regression
ProblemWrite a program to implement linear regression algorithm.User has to enter total number of values.SolutionThe solution to compute the linear regression in C programming language is as follows −Linear regression finds the relationship between two variables by connecting a linear equation to the observed data. One variable is to be an explanatory variable, and the other is a dependent variable.The logic with regards to linear regression is explained below −for(i=0;i
