An algorithm is given below to explain the process which is included in the C programming language to print the characters and strings in different formats.Step 1: Read a character to print.Step 2: Read a name at compile time.Step 3: Output of characters in different formats by using format specifiers.printf("%c%3c%5c", x, x, x);printf("%3c%c", x, x);printf("");Step 4: Output of strings in different formats by using format specifiers.printf("%s", name);printf("%20s", name);printf("%20.10s", name);printf("%.5s", name);printf("%-20.10s", name);printf("%5s", name);ExampleFollowing is the C program to print the characters and strings in different formats − Live Demo#include main(){    char x = 'T';    static char name[20] = "Tutorials Point"; ...

ProblemA laptop manufacturing company has the monthly compensation policy for their salespersons as mentioned below −Minimum base salary: 3000.00Bonus for every computer sold: 200.00Commission on the total monthly sales: 5 per centSince the prices of laptops are changing, the sales price of each laptop is fixed at the beginning of every month.SolutionThe logic for finding the bonus and commission is as follows −bonus = BONUS_RATE * quantity ; commission = COMMISSION * quantity * price ;The gross salary is calculated by using the formula given below −Gross salary = basic salary + (quantity * bonus rate) + (quantity * Price) ...

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

Pointer is a variable that stores the address of another variable.Features of PointersPointer saves the memory space.The execution time of a pointer is faster because of the direct access to a memory location.With the help of pointers, the memory is accessed efficiently i.e. memory is allocated and deallocated dynamically.Pointers are used with data structures.Pointer declaration, initialization and accessingConsider the following statement −int qty = 179;In the memory, the variable can be represented as shown below −DeclarationDeclaring a pointer can be done as shown below −Int *p;It means ‘p’ is a pointer variable which holds the address of another integer variable.InitializationThe ...

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 ...

Sorting is the process of arranging the elements either in ascending (or) descending order. This process is determined for accessing and organizing data quickly. Sorting helps in optimizing search techniques and operations that make the data more readable and accessible. This involves comparing elements that rearrange the readable and accessible determined by criteria. Types of sorting Sorting in C involves different methods that determine the data in a certain order. C language provides five sorting techniques, which are as follows − Bubble sort (or) Exchange Sort Selection sort ... Read More

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 ...

ProblemPrint the American Standard Code for Information Interchange (ASCII) values of 0 to 255 characters without initializing the character to integer type variable. Simply, use the format specifier.SolutionHere we are writing a program to print only from 65 to 122.If you want to see all ASCII values, in for loop you can write as follows −For(i=0;i

ProblemRemove all the extra spaces from an entered string at runtime with the help of while loop by checking the 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 ...
