Following is the program to find factorial of a number using for loop. #include<stdio.h> #include<conio.h> void main() { int fact,i,n; fact = 1; printf(“Enter the number\t”); scanf(“%d” , &n); for(i = 1; i <= n; i++) { fact = fact*i; } printf(“Factorial of %d is %d”, n , fact); getch(); } Output Enter the number …
Following is the program to Reverse a String using for loop. #include<stdio.h> #include<conio.h> void main() { int i, j, k; char str[100]; char rev[100]; printf(“Enter a string\t”); scanf(“%s”, str); printf(“The original string is %s”, str); for(i = 0; str[i] != ‘\0’; i++); { k = i-1; } for(j = 0; j <= i-1; j++) { …

Following is the program to find out sum of digits of a number using loops. #include<stdio.h> #include<conio.h> int sumOfDigit(int num); void main() { int num, sum; clrscr(); printf(“Enter a number\t”); scanf(“%d”, &num); sum = sumOfDigit(num); printf(“The sum of digit %d is %d”, num, sum); getch(); } int sumOfDigit(int num) { int s=0, a, r; a …
#include<stdio.h> #include<conio.h> void sorting(int *x,int y); void main() { int a[5],b,c; clrscr(); printf(“Enter 5 numbers”); for(b = 0; b < 5; b++) { scanf(“%d”,&a[b]); } sorting(a,5); getch(); } void sorting(int *x,int y) { int i,j,temp; for(i = 1; i <= y-1; i++) { for(j = 0; j < y-i; j++) { if(*(x+j) >*(x+j+1)) { temp …
In this program we will swap values of two variables. The values are numeric and we will swap them using different techniques(some tricky ones too). Let’s start with the simplest technique, which is by using atemporary variable #include<stdio.h> #include<conio.h> void main() { int x=10, y=15, temp; temp = x; x = y; y = temp; …
You can do this in many ways, Let’s learn how to do this using recursion. #include<stdio.h> #include<conio.h> int findLargest(int arr[],int size); void main() { int arr[5]; int i, max=0; clrscr(); printf(“Enter 5 numbers\t”); for(i=0; i<5; i++) { scanf(“%d”, &arr[i]); } max = findLargest(arr, 5); printf(“The largest element is %d”, max); getch(); } int findLargest(int *arr,int …

Program to Remove duplicate Element in an Array C program to delete duplicate elements from an array. For example, if an array contains following five elements: 1, 6, 2, 1, 9; in this array ‘1’ occurs two times. After deleting duplicate element we get the following array: 1, 6, 2, 9. C programming code #include …
#include<stdio.h> #include<conio.h> void main() { int a, b, c, s=0; clrscr(); printf(“Enter a number:\t”); scanf(“%d”, &a); c = a; //the number is reversed inside the while loop. while(a > 0) { b = a%10; s = (s*10)+b; a = a/10; } //Here the reversed number is compared with the given number if(s == c) { …
