WHILE LOOP

By
             1.TABLE OF ONE:


#include<stdio.h>
int main()
{
int i=1;
while(i<=10)
{
printf("%d\n",i);
i++;
}
}
•OUTPUT 

1
2
3
4
5
6
7
8
9
10

                 2.PRINT DIGITS OF INTEGER VALUE IN REVERSE ORDER: 


#include<stdio.h>
int main()
{
int no,b;
printf("Enter any number\n");
scanf("%d",&no);
printf("Reverse is given below\n");
while(no!=0)
{
b=no%10;
printf("%d",b);
no=no/10;
}
}

•OUTPUT 

Enter any number 
589
Reverse is given below 
985

                        3.CHECK GIVEN NUMBER IS PALINDROME OR NOT:



#include<stdio.h>
int main()
{
int no,b,rev=0,cpy;
printf("Enter any number\n");
scanf("%d",&no);
cpy=no;
while(no!=0)
{
b=no%10;
rev=rev*10+b;
no=no/10;
}
if(cpy==rev)
printf("Palindrome");
else
printf("Not Palindrome");
}
•OUTPUT 

Enter any number 
5885
Palindrome

        4.FIND SUM OF DIGITS OF INTEGER                                          VALUE: 

#include<stdio.h>
int main()
{
int no,b,sum=0;
printf("Enter any number\n");
scanf("%d",&no);
while(no!=0)
{
b=no%10;
sum=sum+b;
no=no/10;
}
printf("Total sum of digits=%d",sum);
}

#include<stdio.h>
int main()
{
int no,b,m=1;
printf("Enter any number\n");
scanf("%d",&no);
while(no!=0)
{
b=no%10;
m=m*b;
no=no/10;
}
printf("Total multiply of digits=%d",m);
}
•OUTPUT 

Enter any number 
785
Total sum of digits=20

           5.FIND OF MULTIPLY OF INTEGER                                     VALUE:


#include<stdio.h>
int main()
{
int no,b,m=1;
printf("Enter any number\n");
scanf("%d",&no);
while(no!=0)
{
b=no%10;
m=m*b;
no=no/10;
}
printf("Total multiply of digits=%d",m);
}
•OUTPUT 

Enter any number 
325
Total multiply of digits=30

          6.PRINT FIRST AND LAST DIGIT OF                              INTEGER VALUE:



#include<stdio.h>
int main()
{
int no,b,f;
printf("Enter any number\n");
scanf("%d",&no);
f=no%10;
while(no!=0)
{
b=no%10;
no=no/10;
}
printf("First digit=%d and last digit=%d",b,f);
}
•OUTPUT 

Enter any number
 4859
First digit=4 and
Last digit=9

STRUCTURE

By
1.INPUT NAME,ROLL NUMBERS AND MARKS OF STUDENTS AND PRINT USING STRUCTURE: #include<stdio.h> #include<string.h> struct Student { char name[ 200 ]; int rollno; float marks; }; int main () { struct Student obj; strcpy(obj.name= "Anil Singhania" ); obj.rollno= 205 ; obj.marks= 85.4 ; printf( "Name=%s\n" ,obj.name); printf( "Rollno=%d\n" ,obj.rollno); printf( "Marks=%f\n" ,obj.marks); •Output  Name=Anil Singhania Rollno=205; Marks=85.4           2.ADDITION PROGRAMME USING STRUCTURE:  #include<stdio.h> struct Arithmetic { int x; int y; int z; }; int main () { struct Arithmetic obj; obj.y= 20 ; obj.z= 50 ; obj.x=obj.y+obj.z; printf( "Add=%d" ,obj.x); } •OUTPUT  Add=70             3.USER INPUT STRUCTURE:  #include<stdio.h> struct Arithmetic { int x; int y; int z; }; int main () { struct Arithmetic obj; printf(...

FILE HANDLING

By
10.1.1 File Pointers It is not enough to just display the data on the screen. We need to save it because memory is volatile and its contents would be lost once program terminated, so if we need some data again there are two ways one is retype via keyboard to assign it to particular variable, and other is regenerate it via programmatically both options are tedious. At such time it becomes necessary to store the data in a manner that can be later retrieved and displayed either in part or in whole. This medium is usually a ''file'' on the disk. Introduction to file Until now we have been using the functions such as scanf,printf, getch, putch etc to read and write data on the variable and arrays for storing data inside the programs. But this approach poses the following programs. 1. The data is lost when program terminated or variable goes out of scope. 2. Difficulty to use large volume of data. We can overcome these problems by storing data on secondary devices such as Har...
