Even you can use the same function name as strstr(). Note: Here, I am using fstrstr() function that will work as an inbuilt function strstr(). This is one of the top coding questions asked in an interview. Code to implement strstr function in CĬomplete C program to write your own strstr function. I have been asked this question in IBM placement interview on campus. This function will work the same like as inbuilt strstr() function. In C, we use a structure pointer of a file type to declare a file: FILE fp C provides a number of build-in function to perform basic file operations: fopen () - create a new file or open a existing file. Now here, instead of using an inbuilt strstr function, we want to implement a strstr function in C. File handling is one of the most important parts of programming. If it founds substring in the base string, it returns 1. The Second argument is sub-string that need to be searched in base string.
First string contents base string in which we want to search sub-string. This function is very easy to use in c language. Syntax Declaration for strstr function: int strstr(char*, char*) Before to write our own code to implement the strstr function in C, I briefly introduce you an inbuilt strstr function with its syntax. This function is used to find the substring in other string. Strstr is the inbuilt string function given in C language. What does strstr function do? What are its uses? What is strstr function in C? Now press Esc to return to the turbo c++ console.Before implementing strstr function, first thing, you need to understand strstr function. You can view the user screen any time by pressing the alt+f5 keys. You will see the following output on user screen. Or, press ctrl+f9 keys compile and run the program directly. Then click on the run menu then run sub menu to run the c++ program. Now click on the compile menu then compile sub menu to compile the c++ program. There are 2 ways to compile and run the C++ program, by menu and by shortcut. Until you press any key, it blocks the screen. Getch() The getch() function asks for a single character.
The void keyword specifies that it returns no value.Ĭout << "Welcome to C++ Programming." is used to print the data "Welcome to C++ Programming." on the console. Void main() The main() function is the entry point of every program in C++ language. The getch() function is defined in conio.h file. #include includes the console input output library functions. It provides cin and cout methods for reading from input and writing to output respectively.
