Problem Solving Through Programming in C

Week-04: Program-01

Due Date of Submission 2022-02-24, 23:59 IST

Write a C Program to Find the Smallest Number among Three Numbers (integer values) using Nested IF-Else statement.

#include <stdio.h>

int main()

{

    int n1, n2, n3; 

    scanf("%d %d %d", &n1, &n2, &n3);

--Solution-- 

  if(n1<n2 && n1<n3){ printf("%d is the smallest number.", n1); } else{ if(n2<n1 && n2<n3){ printf("%d is the smallest number.", n2); } else{ printf("%d is the smallest number.", n3); } } }

Week-04: Program-02

Due Date of Submission 2022-02-24, 23:59 IST

Write a C program to find power of a number using while loops. The base number (>0) and exponent (>=0) is taken from the test cases.

#include <stdio.h>

int main()

{

int base, exponent;

long int result;

scanf("%d", &base); 

scanf("%d", &exponent);

--Solution-- 

  result=1; while(exponent!=0){ result=result*base; exponent--; }

Week-04 Program-03

Due Date of Submission 2022-02-24, 23:59 IST

Write a C program to calculate the Sum of First and the Last Digit of a given Number. For example if the number is 1234 the result is 1+4 = 5.

#include <stdio.h>

int main()

{

int N, First_digit, Last_digit;

scanf("%d", &N);

--Solution-- 

  Last_digit=N%10; while(N>=10){ N=N/10; } First_digit=N;

Week-04 Program-04

Due Date of Submission 2022-02-24, 23:59 IST

Write a program to find the factorial of a given number using while loop.

#include<stdio.h>

void main()

{

    int n;

    long int fact;  /* n is the number whose factorial we have to find and fact is the factorial */

    scanf("%d",&n);

--Solution-- 

  int i=1; fact=1; while(i<=n){ fact=fact*i; i++; } printf("The Factorial of %d is : %ld",n,fact); }
