java Simple
Hello Java
To run the java program first write the code in notepad and save it with the extension .java
and then open command prompt and compile the program (eg : javac Simple.java) After the compilation, to run the java code we need to call the Java interpreter ,to call the java interpreter we use java command and u need to [ass the filename you know which contains the byte code(eg:- java Simple)
#include <stdio.h>
#include <stdlib.h>
int main()
{
char ch='B';
int n=ch;
printf("The ASCII code of the character %c is : %d\n",ch,n);
return 0;
}
OUTPUT
The ASCII code of the character B is : 66
PROGRAM
#include <stdio.h>
#include <stdlib.h>
int main()
{
int n1=2598;
float n2=n1;
printf("The float value is : %.2f",n2);
return 0;
}
OUTPUT
The float value is: 2598.00
PROGRAM
#include <stdio.h>
#include <stdlib.h>
int main()
{
int n1,n2;
printf("Enter two numbers");
scanf("%d%d",&n1,&n2);
if(n1%n2==0)
printf("second number is factor of first number");
else
printf("second number is not factor of first number");
return 0;
}
OUTPUT
Enter two numbers 12 6
second number is factor of first number
