Online compiler c for windows

Online C Compiler is a web-based tool powered by ACE code editor. This tool can be used to learn, build, run, test your programs. You can open the code from your local and continue to build using this IDE. Code and the output can be downloaded.

C is a general purpose programming language, one of the powerful language that has inspired and influenced many other languages like Java, Python, Perl, Java, PHP, Ruby. C is widely used to build operating systemns and embedded system applications. Its origin is closely tied to the development of UNIX operating system. Compilers and Interpreter of many other programming languages are implemented using C. Its basic features and the control structures are directly and indirectly adopted by other programming languages.

C was originally developed at Bell Labs by Dennis Ritchie between 1972 and 1973. It was successor to the programming language B. Around 1980, C has become most widely used programming language. C provides contructs that maps the high level program to machine instrutions more efficiently which makes it one of the fastest in terms of code execution.

C Language online compiler

Write, Run & Share C Language code online using OneCompiler’s C online compiler for free. It’s one of the robust, feature-rich online compilers for C language, running the latest C version which is C18. Getting started with the OneCompiler’s C editor is really simple and pretty fast. The editor shows sample boilerplate code when you choose language as ‘C’ and start coding!

Read inputs from stdin

OneCompiler’s C online editor supports stdin and users can give inputs to programs using the STDIN textbox under the I/O tab. Following is a sample C program which takes name as input and print your name with hello.

#include <stdio.h>
int main()
{
    char name[50];
    printf("Enter name:");
    scanf("%s", &name);
    printf("Hello %s" , name );
    return 0;
    
}

About C

C language is one of the most popular general-purpose programming language developed by Dennis Ritchie at Bell laboratories for UNIX operating system. The initial release of C Language was in the year 1972. Most of the desktop operating systems are written in C Language.

Key features:

• Structured Programming
• Popular system programming language
• UNIX, MySQL and Oracle are completely written in C.
• Supports variety of platforms
• Efficient and also handle low-level activities.
• As fast as assembly language and hence used as system development language.

Syntax help

Loops

1. If-Else:

When ever you want to perform a set of operations based on a condition if-else is used.

if(conditional-expression) {
   // code
} else {
   // code
}

You can also use if-else for nested Ifs and if-else-if ladder when multiple conditions are to be performed on a single variable.

2. Switch:

Switch is an alternative to if-else-if ladder.

switch(conditional-expression) {    
case value1:    
 // code    
 break;  // optional  
case value2:    
 // code    
 break;  // optional  
...    
    
default:     
 // code to be executed when all the above cases are not matched;    
} 

3. For:

For loop is used to iterate a set of statements based on a condition.

for(Initialization; Condition; Increment/decrement){  
  // code  
} 

4. While:

While is also used to iterate a set of statements based on a condition. Usually while is preferred when number of iterations are not known in advance.

while(condition) {  
 // code 
}  

5. Do-While:

Do-while is also used to iterate a set of statements based on a condition. It is mostly used when you need to execute the statements atleast once.

do {
  // code 
} while (condition); 

Arrays

Array is a collection of similar data which is stored in continuous memory addresses. Array values can be fetched using index. Index starts from 0 to size-1.

Syntax

One dimentional Array:

data-type array-name[size];

Two dimensional array:

data-type array-name[size][size];

Functions

Function is a sub-routine which contains set of statements. Usually functions are written when multiple calls are required to same set of statements which increases re-usuability and modularity.

Two types of functions are present in C

1. Library Functions:

Library functions are the in-built functions which are declared in header files like printf(),scanf(),puts(),gets() etc.,

1. User defined functions:

User defined functions are the ones which are written by the programmer based on the requirement.

How to declare a Function

return_type function_name(parameters);

How to call a Function

function_name (parameters)

How to define a Function

return_type function_name(parameters) {  
  //code
}
