SUM AND AVERAGE

Program number# 1

            Program that takes 3 inputs and process it for sum and average and its printout.

Program:

void main (void)

{

  int num1, num2, num3, sum;

  float avg;

  printf(“enter 1^st  number”);

  scanf(“%d”,&num1);

  printf(“enter 2^nd   number”);

  scanf(“%d”,&num2);

  printf(“enter 3^rd   number”);

  scanf(“%d”,&num3);

 sum= num1+num2+num3;

avg=sum/3.0;

printf(“sum of given number is =%d \n average of given number is = %f”, sum, avg);

}

                                    CONDITIONAL PROGRAM

                                    LOSS AND PROFIT

Program number# 2

            Program that determine loss and profit

Program:

  void main (void

{

 int sale, cost;

  printf(“enter cost price”);

  scanf(“%d”, &cost);

  printf(“enter sale price”);

  scanf(“%d”, &sale);

  if (sale > cost)

  printf(“you are in profit”);

  else

  printf(“you are in loss”);

}

                                    PERCENTAGE AND GRADE

Program number# 3  

            Program that determine percentage and grade

Program:

void main ()

{

  int math, physic, chemistry, computer, total, sum, percentage;

  printf(“enter number obtained in math”);

  scanf(“%d”, &math);

  printf(“enter number obtained in physic”);

  scanf(“%d”, &physic);

  printf(“enter number obtained in chemistry”);

  scanf(“%d”, &chemistry);

  printf(“enter number obtained in computer”);

  scanf(“%d”, &computer);

  printf(“enter total number”);

   scanf(“%d”, &total);

   sum= math+ physic+ chemistry+ computer;

  percentage= sum/total*100;

  if (percentage> = 80)

  printf(“A+”);

 else  if (percentage > = 70 && percentage < =79)

  printf(“A”);

 else  if (percentage > = 60 && percentage < =69)

  printf(“B”);

else  if (percentage > = 50 && percentage < =59)

  printf(“C”);

else  if (percentage > = 40 && percentage < =49)

  printf(“D”);

 else if (percentage > = 33 && percentage < =39)

  printf(“E”);

else  if (percentage < =32)

  printf(“FAIL”);

else

  printf(“invalid numbers”);

}

                                    EVEN OR ODD NUMBER

Program number# 4

            Program which determine even or odd number

Program:

void main (void)

int num, mod;

prnitf(“enter a number”);

scanf(“%d”, &num);

mod=num%2;

if(mod ==0 )

printf(“the entered number is even ”);

else if(mod==1)

printf(“the entered number is odd”);

else

printf(“the entered is invalid”);

}

ITERATION PROGRAM

NAME PRINT

Program number# 5

            A program which print and name or statement number of times

Program:

  void main (void)

{

int a:

for (a=1;a<=10;a=a++)

printf(“its thrown out gadgets”);

}

This program will print the sentence ‘its thrown out gadgets’ 10 times.

                                                TABLE

Program number# 6

            Program which print table of given number.

Program:

void main(void)

{

int num, product,a;

printf(“enter a number ”);

scanf(“%d”, &num);

for (a=1;a<=10;a=a++)

{

product= num*a;

printf (“%d x %d = %d”, num, a, product );

}

}
