C 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 MoreHow communication among functions is established in C language?
Functions communicate among themselves with the help of arguments and return value.Farm of ‘C’ function is as follows −return-datatype function name (argument list){ local variable declarations; executable statements(s); return (expression); }For example, void mul (int x, int y){ int p; p=x*y; printf("product = %d”, p); }Return values and their typesA function may or may not send back a value to the calling function.It will be done by using the return statementThe return types are void, int, float, char and double.If a function is not returning any value, then its return type is ‘void’.Function nameA ...

ProblemHow to print the long lines into two or more short lines based on specified length in the program using C Language?SolutionLet’s write a code to read a long line and print into two or more short lines according to the mentioned size in the program.The built in functions that we take in this program readline() function, is used to store text in array and returns the size of line.The logic we use to read a short sentence is explained below −while((charcter=readtext())>0){ if(charcter>length){ count=0; a=0; while(alength){ count=0; a=0; while(a
Read MoreLimitations of C programming language
ProblemWhat are the limitations of C Programming when compared to other programming languages?SolutionC Language prevents or prohibits the concepts of object-oriented programming language like inheritance, polymorphism, encapsulation, and data abstraction.C programming language does not detect errors for every line of coding, it will check the bugs after the complete coding is done.It does not exhibit namespace property.C programming has an insufficient level for data abstraction, i.e., does not have very large data handling capacity.C Language does not allow the user to detect the errors with the help of exception handling features.The constructor and destructors concept is not supported by the ...

ProblemWrite a C program for storing the details of 5 students into a file and print the same using fread() and fwrite()SolutionThe fread() function reads the entire record at a time.Syntaxfread( & structure variable, size of (structure variable), no of records, file pointer);Examplestruct emp{ int eno; char ename [30]; float sal; } e; FILE *fp; fread (&e, sizeof (e), 1, fp);The fwrite() function writes an entire record at a time.Syntaxfwrite( & structure variable , size of structure variable, no of records, file pointer);Examplestruct emp{ int eno: char ename [30]; float sal; } e; FILE ...
Read MoreConcatenating n characters from source string to destination string in C
ProblemWrite a C program to concatenate n characters from source string to destination string using strncat library functionSolutionThe strcat functionThis function is used for combining or concatenating two strings.The length of the destination string must be greater than the source string.The resultant concatenated string will be in the source string.Syntaxstrcat (Destination String, Source string);Example 1#include main(){ char a[50] = "Hello"; char b[20] = "Good Morning"; clrscr ( ); strcat (a, b); printf("concatenated string = %s", a); getch ( ); }OutputConcatenated string = Hello Good MorningThe strncat functionThis function is used for combining or ...
