Problem Solving Through Programming in C

Week-04 Program-01

Last Day of Submission: 25-Aug-2022

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

--Solution-- 

  /*#include <stdio.h> int main() { int n1, n2, n3; scanf("%d %d %d", &n1, &n2, &n3);*/ if(n1<n2 && n1<n3){ printf("%d is the smallest number.", n1); } else { if(n2<n3 && n2<n1){ printf("%d is the smallest number.", n2); } else{ printf("%d is the smallest number.", n3); } } return 0; }

Week-04 Program-02

Last Day of Submission: 25-Aug-2022

Write a program to find whether a given character is a Vowel or consonant. A character is taken as input. The character may be in Upper Case or in Lower Case.

--Solution-- 

  /*#include <stdio.h> int main() { char ch; scanf("%c",&ch);*/ if(ch=='a' || ch=='e' || ch=='i' || ch=='o' || ch=='u' || ch=='A' || ch=='E' || ch=='I' || ch=='O' || ch=='U'){ printf("%c is a vowel.", ch); } else{ printf("%c is a consonant.", ch); } return 0; }

Week-04 Program-03

Last Day of Submission: 25-Aug-2022

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.

--Solution-- 

  /*#include <stdio.h> int main() { int N, First_digit, Last_digit; scanf("%d", &N);*/ int a=N; while(a!=0){ if(a==N){First_digit=a%10;} if(a<10){Last_digit=a%10;} a=a/10; } /*printf("Sum of First and Last digit = %d", First_digit + Last_digit); return 0; }*/

Week-04 Program-04

Last Day of Submission: 25-Aug-2022

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.

--Solution-- 

  /*#include <stdio.h> int main() { int base, exponent; long int result; scanf("%d", &base); scanf("%d", &exponent);*/ result=1; for(int i=0; i<exponent; i++){result=result*base;} /*printf("The result is : %ld\n", result); return 0; }*/
