programming C(repetition)

  flow chart to display the following number series(while)

#include <stdio.h>

int main()

{

  int counter=1;

  while(counter<=100)

  {

      printf("%d",counter);

      counter++;

  }

}

    

   

                                                                                                                                

fun code (this is error not correct code only for funny)      

                                                                                                                   

while("counter<=100 \n")

add this one for "while" part

programming C( selection)

  input admission number,a module mark and display admission number with grade(if ,else if content)

marks      grade

>=75         A

65-75        B

55-65        C

<55           F

ex:

 #include <stdio.h>

#include <stdlib.h>

int main()

{

  int admno,marks;

  char grade;

  printf("enter admission number");

  scanf("%d",&admno);

  printf("enter module mark");

  scanf("%d",&marks);

  if (marks>=75)

  grade='A';

  else if (marks>=65)

  grade='B';

  else if (marks>=55)

  grade='C';

  else

  grade='F';

  printf("admission number %d grade is %c \n ",admno,grade);

}

   

programming C(switch structure)

   in put a character and display the vowel or not

(switch content)

#include <stdio.h>

#include <stdlib.h>

int main()

{

   char ch;

   printf("enter a character");

   scanf("%c",&ch);

   switch(ch)

   {

       case 'a':printf("a is a vowel");break;

       case 'e':printf("e is a vowel");break;

       case 'i':printf("i is a vowel");break;

       case 'o':printf("o is a vowel");break;

       case 'u':printf("u is a vowel");break;

       default:printf("%c is not a   vowel",ch);

   }

}

     

programming C( switch structure)

   even number and odd number(if and switch content)

if content

#include <stdio.h>

#include <stdlib.h>

int main()

{

    int no,ans;

    printf("enter a number");

    scanf("%d",&no);

    ans=no%2;

    if(ans==0)

    printf("%d is an even number",no);

    else

    printf("%d is an odd number",no);

    return 0;

}

write the above programe using switch

#include <stdio.h>

#include <stdlib.h>

int main()

{

   int no,ans;

   printf("enter a number");

   scanf("%d",&no);

   ans=no%2;

   switch(ans)

   {

       case 0:printf("%d is an even",no);break;

       case 1:printf("%d is an odd",no);break;

   }

}

 

    

programming C( switch structure)

  enter month number and display the name of the month(switch content)

#include <stdio.h>

#include <stdlib.h>

int main()

{

    int opt;

    printf("enter month number");

    scanf("%d",&opt);

    switch(opt){

    case 1:printf("january");break;

    case 2:printf("february");break;

    case 3:printf("march");break;

    case 4:printf("april");break;

    case 5:printf("may");break;

    case 6:printf("june");break;

    case 7:printf("july");break;

    case 8:printf("august");break;

    case 9:printf("september");break;

    case 10:printf("october");break;

    case 11:printf("november");break;

    case 12:printf("december");break;

    default :printf("invalid month number");

    }
