Write a ‘C’ Program to compute the sum of all elements stored in an array using pointers

#include

#include

void main()

{

int numarray[10];

int i,sum=0;

int *ptr;

printf("\n Enter 10 elements: ");

for(i=0;i<10 i="" span="">

scanf("%d",&numarray[i]);

ptr=numarray;

for(i=0;i<10 i="" span="">

{

sum=sum+*ptr;

ptr++;

}

printf("The sum of array elements :%d",sum);

return(0);

}

Output

Enter 10 elements : 11   12      13      14      15      16      17      18      19      20

The sum of array elements is 155

C Program for Exponent Series

#include

#include

void main()

{

int n,count;

float x, term,sum;

printf("\n Enter value of x: ");

scanf("%f",&x);

n=term=sum=count=1;

while(n<=100)

{

term=term*x/n;

sum=sum+term;

count=count+1;

if(term

n=999;

else

n=n+1;

}

printf("\n Terms =%d sum = %f", count,sum);

return 0;

}

Output

Enter value of x : 0

Terms =2 sum=1.000000

Enter value of x : 0.1

Terms =5 sum=1.105171

Enter value of x : 0.5

Terms =7 sum=1.648720

Enter value of x : 0.75

Terms =8 sum=2.116997

Enter value of x : 0.99

Terms =9 sum=2.691232

Enter value of x : 1

Terms =9 sum=2.718279

Program to convert temperature from degree centigrade to Fahrenheit

#include

#include

int main()

 {

    float celsius, fahrenheit;

    printf("\nEnter temp in Celsius : ");

    scanf("%f", &celsius);

    fahrenheit = (1.8 * celsius) + 32;

    printf("\nTemperature in Fahrenheit : %f ", fahrenheit);

     return (0);

}

Output

Enter temp in Celsius : 32

Temperature in Fahrenheit : 89.59998

C Program to find the simple interest

#include

#include 

int main()

 {

   int amount, rate, time, si;

   printf("\nEnter Principal Amount : ");

   scanf("%d", &amount);

   printf("\nEnter Rate of Interest : ");

   scanf("%d", &rate);

   printf("\nEnter Period of Time   : ");

   scanf("%d", &time);

   si = (amount * rate * time) / 100;

   printf("\nSimple Interest : %d", si);

   return(0);

}

Output

Enter Principal Amount : 500

Enter Rate of interest : 5

Enter Period of Time   : 2

Simple Interest : 50

C Program to find sum of two numbers

#include

#include 

int main()

 {

   int a, b, sum;

   printf("\nEnter two no: ");

   scanf("%d %d", &a, &b);

   sum = a + b;

   printf("Sum : %d", sum);

   return(0);

}

Output

Enter two no: 5 6

Sum : 11

To obtain solution of second order quadratic equation

#include

#include

#include

int main()

{

   float a, b, c;

   float desc, root1, root2;

   printf("\nEnter the Values of a : ");

   scanf("%f", &a);

   printf("\nEnter the Values of b : ");

   scanf("%f", &b);

   printf("\nEnter the Values of c : ");

   scanf("%f", &c);

   desc = sqrt(b * b - 4 * a * c);

   root1 = (-b + desc) / (2.0 * a);

   root2 = (-b - desc) / (2.0 * a);

   printf("\nFirst Root : %f", root1);

   printf("\nSecond Root : %f", root2);

   return (0);

}

Output

Enter the Values of a : 1

Enter the Values of a : -5

Enter the Values of a : 6

First Root : 3.000000

Second Root : 2.000000

Find Factorial of Number Using Recursion

#include

#include

int fact(int);

int main()

{

   int factorial, num;

   printf("Enter the value of num :");

   scanf("%d", &num);

   factorial = fact(num);

   printf("Factorial is %d", factorial);

   return (0);

}

int fact(int n)

{

   if (n == 0)

{

      return (1);

   }

   return (n * fact(n - 1));

}
