C Tutorials for Beginners

Here are some latest trends in programming.  Light-weight syntax means using shorter keywords and more symbols Light-weight functions (aka lambdas/closures/blocks) are almost ubiquitous in new languages, sometimes with highly abbreviated syntax (like Scala/Swift placeholder syntax) Light-weight objects (objects you construct without declaring a new class/type) Light-weight threads (green threads / cooperative multithreading)

Below is a very simple program to find the arithmetic operator. Please feel free to put a comment if need an explanation. #include #include void main()   {     float a1,a2;     char operator;     printf("\n Enter the values of a1 operator a2\n");     scanf("%f%c%f",&a1,&operator,&a2);     switch(operator)      { case '+': printf("%.2f",a1+a2); break; case '-':  printf("%.2f",a1-a2);  break; case '*':  printf("%.2f",a1*a2); break; case '/':  if(a2==0)  printf("error\n");  else  printf("%.2f",a1/a2);  break; default: printf("unknown operatotr\n"); break;      }    }

Though this site aims at understanding C language, I am writing a program for you in C++, to have a general idea about C++ too. A program in C++,to calculate the average of two numbers, which are entered by the keyboard while the execution of the program. Try to understand the program; #include &lt iostream &gt using namespace std; int main() {     float num1,num2,average,sum;     cout << "Enter the first number:";     cin >> num1;     cout << "Enter the second number:";     cin >> num2;     sum=num1+num2;     average=sum/2;     cout << "The sum of the two numbers is:"<< sum<<"\n"<<"The average of the two numbers is:" << average; return(0); } Explaination: The new file header used here in this C++ program is the #include . By this , we are asking the preprocessor to add the contents of the iostream file to our program. The program is written in the

Android is one of the most rapidly growing mobile platform today. Most of us are opting for android devices , cell phones /tablets and so am I . While surfing around the Android Market (The place to download android apps) I came across an helpful app; " C Reference ".                                This app provides the reference to the standard C library. It also contains description of all the functions and macros in C, in a searchable from. This app could be very handy in while writing C programs.And the best part about this app is that , this app can be downloaded free from the android market. Screenshots: You can see and download this app from C Reference App

Check out , the link below takes to the page that has a C code , which creates animation with just three lines of C code. Quite interesting http://a1k0n.net/2011/06/26/obfuscated-c-yahoo-logo.html

Below is a program to print the average of two numbers that are input through the keyboard.   /* Read the numbers from the keyboard as input and * print out their average as output. */    #include &lt stdio &gt int main( ) { double x = 0.0, sum = 0.0; int count = 0; printf( "\t--- Calculate Average of the numbers ---\n" ); printf( "\nEnter the number you want to calulate average for:\n" "(Type a letter to end your input)\n" ); while ( scanf( "%lf", &x ) == 1 ) { sum += x; ++count; } if ( count == 0 ) printf( "No input data given!\n" ); else printf( "The average of given numbers is %.2f\n", sum/count ); return 0; } The output of the program:
