C program to find out cosine and sine values using math.h library.
ProblemTo find the cosine and sine values for every 10 degrees from 0 to 150.SolutionThe logic used to find the cosine values is as follows −Declare MAX and PI value at the starting of a programwhile(angle
Read MoreWrite a C program to print all files and folders.
File is a collection of records (or) a place on hard disk where the data is stored permanently.By using C commands, we can access the files in different ways.Operations on filesGiven below are the operations which can be performed on files in the C programming language −Naming the fileOpening the fileReading from the fileWriting into the fileClosing the fileSyntaxThe syntax for opening and naming a file respectively is given below −FILE *File pointer;For example, FILE * fptr;File pointer = fopen (“File name”, “mode”);For example, fptr = fopen (“sample.txt”, “r”);FILE *fp; fp = fopen (“sample.txt”, “w”);The syntax for reading from file ...
Read MoreC program to print the ASCII values in a string.
An array of characters is called a string.Given below is the declaration of a string −char stringname [size];For example, char string[50]; string of length 50 characters.InitializationUsing single character constant.char string[10] = { ‘H’, ‘e’, ‘l’, ‘l’, ‘o’ ,‘\0’}Using string constants.char string[10] = “Hello”:;AccessingThere is a control string “%s” used for accessing the string till it encounters ‘\0’.The logic we used to print the ASCII values of a given string at runtime is as follows −while(str[i]!='\0'){ printf("ASCII Value of %c = %d", str[i], str[i]); i++; }ExampleFollowing is the C program to print the ASCII values of a given string ...
Read MoreC program to remove spaces in a sentence using string concepts.
ProblemRemove all the spaces from an entered string at runtime with the help of while loop by checking spaces at each index of a character.SolutionConsider an example given below −It removes all the spaces from a given string. The given string is Tutorials Point C Programming. The result after removing spaces is TutorialsPointCProgramming.An array of characters is called a string.Given below is the declaration of a string −char stringname [size];For example, char string[50]; string of length 50 characters.InitializationUsing single character constant.char string[10] = { ‘H’, ‘e’, ‘l’, ‘l’, ‘o’ ,‘\0’}Using string constants.char string[10] = “Hello”:;AccessingThere is a control string “%s” ...
Read MoreDeletion of head and tail element logic in a linked list using C language.
Linked lists use dynamic memory allocation i.e. they grow and shrink accordingly. It is collection of nodes.Node has two parts, which are data and link. These are explained below.Operations on linked listsThere are three types of operations on linked lists which are as follows −InsertionDeletionTraversingDeletionIdentify the node.Adjust the links in such a way that deallocation of the nodes does not make the list as unconnected components.Return/display element to delete.Deallocate the memory.Delete Head elementFollow the steps given below to delete a head element in C programming language.1. void del_head() 2. { 3. int x; Node *temp; 4. if(Head==NULL) 5. { ...
Read MoreConvert vowels from upper to lower or lower to upper using C program
An array of characters is called a string.DeclarationFollowing is the declaration for an array −char stringname [size];For example − char a[50]; string of length 50 charactersInitializationUsing single character constant −char a[10] = { ‘H’, ‘e’, ‘l’, ‘l’, ‘o’ ,‘\0’}Using string constants −char a[10] = "Hello":;AccessingThere is a control string "%s" used for accessing the string till it encounters ‘\0’.The logic used to convert vowels from upper to lower or lower to upper is −for(i=0;string[i]!='\0';i++){ if(string[i]=='a'||string[i]=='e'||string[i]=='i'||string[i]=='o'||string[i]=='u'){ string[i]=toupper(string[i]); } } printf("The result string with converted vowels is : "); puts(string);ProgramFollowing is the C program using conversion functions ...
Read MoreC Program to print the sum of boundary elements of a matrix
Given a matrix, we need to print the boundary elements of the matrix and display their sum.ExampleRefer the matrix given below −Given matrix1 2 3 4 5 6 7 8 9Boundary Matrix1 2 3 4 6 7 8 9Sum of boundary elements: 1 + 2 + 3 + 4 + 6 + 7 + 8 + 9 = 40The logic to find the sum of boundary matrix is as follows −for(i = 0; i
Read MoreC program to calculate power of a given number
Take two integers from the user for base and exponent and calculate the power as explained below.ExampleConsider the following for writing a C program.Suppose base =3Exponent = 4Power=3*3*3*3AlgorithmFollow the algorithm given below −Step 1: Declare int and long variables. Step 2: Enter base value through console. Step 3: Enter exponent value through console. Step 4: While loop. Exponent !=0 i. Value *=base ii. –exponent Step 5: Print the result.ExampleThe following program explains how to calculate power of given number in C language.#include int main(){ int base, exponent; long value = 1; printf("Enter a base value: ...
