Putchar function >> Displaying String in C
Putchar function : Displaying String in C Programming Syntax : int putchar(int c); Way 1 : Taking Character as Parameter putchar(‘a’) ; // Displays : a Individual Character is Given as parameter to this function. We have to explicitly mention Character. Way 2 : Taking Variable as Parameter putchar(a); // Display Character Stored in a(…)

Getchar : Reading or Accepting String Character by Character
getchar() : Reading or Accepting String Character by Character In C Programming we have many input/output functions that are useful for accepting input from the user. i.e scanf() | gets(). Getchar() function is also one of the function which is used to accept the single character from the user. Syntax for Accepting String and Working(…)
gets() function : Accepting String from User in C Programming
gets() function : Reading or Accepting String From User in C Reads characters from the standard input (stdin) and stores them as a C string into str until a newline character or the end-of-file is reached. Syntax for Accepting String : char * gets ( char * str ); OR gets( <variable-name> ) Live Example(…)
Initializing String / Charater Array in C Programming
In the previous chapter we have learnt about declaring array of character i.e String. In this chapter we are looking one step forward - Initializing the String and Different ways of Initializing String. Initializing String [Character Array] : Whenever we declare a String then it will contain garbage values inside it. We have to initialize(…)
