Q.1: Write a C Program to Find the Smallest Number among Three Numbers (integer values) using Nested IF-Else statement.

Code:

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; }

Q.2: 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.

Code:

First_digit=N%10; while(N!=0){ Last_digit=N%10; N/=10; }

Q.4: 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.

Code:

result=1.0; while(exponent!=0){ result*=base; exponent--; }
