C Program To Calculate Compound Interest You need to know : Arithmetic operators. Data type. BODMAS rule.                // To know precedence of an operator. Basic input and output system. Formula Of Compound Interest : Compound Interest = Principle * (1 + Rate / 100 )^T or ci  =  p * pow ( ( 1 + r / 100 ) , t ) Wondering what is pow!!   We got it covered, click here . Tips To Do The Program : Take input of principle amount from user. store in a variable like principle. Do same from Time and Rate. Store it in some appropriate variables like time and rate. Now calculate the Compound Interest using the above formula and store it in a variable say ci. Lastly, show the value of ci to the user. Don't forget to optimize the program for a good look and output. Code : #include<stdio.h> #include<math.h> void main() {       ...

Write a C Program to Sort an array using Bubble sort , User Define Array : Code: #include<stdio.h> void main() { int a[20]; int n,i,j,k; printf("Enter the size of array [20]:\n"); scanf("%d",&n); printf("Enter the elements:\n"); for(i=0;i<n;i++) scanf("%d",&a[i]); for(i=0;i<n;i++) for(j=0;j<n-1;j++) { if(a[j]>a[j+1]) { k=a[j]; a[j]=a[j+1]; a[j+1]=k; } } for(i=0;i<n;i++) printf("%d\t",a[i]); } Output: ---------------------------------------------------------------------------- Bubble sort : Using Pointer

Write a C Program on Binary Search from user input Elements : Concept of Binary Search: Binary search compares the value assign before to the middle element present of the array. How to perform Binary Search: Whole sorted array divides repeatedly into half by comparing values in array. If the value is less than the item in the middle of the interval,the search will go the interval to the lower half. Otherwise it will do to the upper half of array. Code:  #include<stdio.h> void main() { int a[20],i,se,ln,u,m,l; printf("Enter length of array:\n"); scanf("%d",&ln); printf("Enter the elements of array:\n"); for(i=0;i<ln;i++) { scanf("%d",&a[i]); } printf("Enter the elements to be search:\n"); scanf("%d",&se); l=0; u=ln-1; while(l<=u) { m=(l+u)/2; if(a[m]==se) break; else if(a[m]<se) ...

Write a C Program to Find Factorial User given using Recursion :   About factorial: 5! = 5!x4!x3!x2!x1! = 120 Code: #include<stdio.h> void main() { int facto(int); int n,b; printf("Enter a range of factorial:\n"); scanf("%d",&n); b=facto(n); printf("\nThe factorial of %d is %d",n,b); } int facto(int n) { if(n==1) return n; else n=n*facto(n-1); return n; } Output:
