C - Input/Output

#include <stdio.h>
int main()
{
    int testInteger;
    printf("Enter an integer: ");
    scanf("%d",&testInteger); 
    printf("Number = %d",testInteger);
    return 0;

}

Above program shows how we can input value to a program and how to print that value entered.
%d is used to indicate integer input or output.
Same as that we use,
  • %f - float
  • %c or %s - char
  • %f - double

Programming with Java

Java is the second most used programming language in the world. Java is a object oriented programming language. Characteristics of java Object oriented language Platform independent. Strongly-typed language. Interpreted and compiled language. Automatic memory management. Every java program is run on the Java Virtual Machine(JVM). It is the foundation of java platform and it is responsible for executing the byte codes and for fundamental capabilities of java. About Java programs, it is very important to keep in mind the following points.  1. Case Sensitivity - Java is case sensitive, which means identifier Hello and hello would have different meaning in Java.  2. Class Names - For all class names the first letter should be in Upper Case.  If several words are used to form a name of the class, each inner word's first letter should be in Upper Case.  Example : class MyFirstJavaClass   3. Method Names - All method names should start with a Lower Case letter.

C- Control Structures

A control structure defines the execution order of the given program statements. There are three types of control structures. Sequence (Linear) Selection Repetition (Iteration) Selection Structure In C language we can use the If and Switch statements to represent the selection structure. If statement also come in two ways. 1. if(condition){      statement;    }    else{     statement;    } 2. if(condition){      statement;    }    else if{     statement;    }    else{     statement;    } This second way is called as nested if statement. and also there can be only a if condition in a program. ex:  1. #include <stdio.h> #include <stdlib.h> int main() {     int no1,no2;     printf("enter two numbers");     scanf("%d %d",&no1,&no2);     if(no1>no2){         printf("highest is %d \n",no1);     }     else{         printf("highest is %d \n",no2

C - Functions

Image
C language is a function oriented programming language. When you develop a program ,you can create your own function or you can use existing functions. The main advantage of using a function is re usability. How to use existing functions main() is also a inbuilt function. There are some math library functions are included in C. Let's see how can we use such a function from a example. Output In the above code i have called the math.h library function inorder to call a inbuild math library function. It is the only alternation i have done to this code rather than the examples i have done before. Also by giving as '%.2f ' I have given a limit to display the float value. If i haven't given a limit,the float value will display fully as you can see below. And we should call the function to find the output of the input variable 'v '. Function calling is done at the last printf statement as sqrt(v). The syntax of declaring a function.
