PROGRAMMING FOR PROBLEM SOLVING LAB : Program 4

 4.  Write the program for the simple, compound interest.

#include<stdio.h> 
#include<math.h> 
void main()
{
int n;
float p,q,r,SI=0,CI=0; 
clrscr();
printf("\n Enter the value of Principal p = "); 
scanf("%f",&p);
printf("\n Enter the value of Rate r = "); 
scanf("%f",&r);
printf("\n Enter the value of Period in year n = "); 
scanf("%d",&n);
SI = ((p*r*n)/100);
printf("\n Simple Interest SI=%f \n",SI); 
q = 1+(r/100);
CI=p*pow(q,n)-p;
printf("\n Compound Interest CI=%f \n",CI); 
getch();
}

OUTPUT:

Enter the value of Principal p = 3500
Enter the value of Rate r = 4
Enter the value of Period in year n = 2
Simple Interest SI=280.000000 
 Compound Interest CI=285.599731

Learning and Development Interview Questions and answers for Mathematics-1.

  1). What is Mean, Mode and Median? Solution Answer: The mean is the average of a  collection of numbers or terms in a sequence. To calculate the mean use a formula is sum of total terms divided  by number of terms. The mode  is the most f requent number or term in a sequence. It means the number that occurred  highest number of times  in a sequence. To find the mode arrange the numbers in ascending or descending order and verify which number repeated most number of times in a sorted sequence. The median is the middle number/term where the sequence is arranged in ascending or descending order. If the sorted sequence have odd number of terms then  divide by 2 and round up to get the position of the median number.  If the  sorted sequence  have  even  number of terms then  divide by 2  to get the position of the median number.  2 ). What is the Difference between Fractional and Rational number? Solu...
