NPTEL Problem Solving Through Programming In C WEEK 4 Assignment 2022

NPTEL Problem solving through Programming In C Week 4 All Programming Assignment Solutions | Swayam 2022. With the growth of Information and Communication Technology, there is a need to develop large and complex software.

This course is aimed at enabling the students to:
• Formulate simple algorithms for arithmetic and logical problems
• Translate the algorithms to programs (in C language)
• Test and execute the programs and  correct syntax and logical errors
• Implement conditional branching, iteration and recursion
• Decompose a problem into functions and synthesize a complete program using divide and conquer approach
• Use arrays, pointers and structures to formulate algorithms and programs
• Apply programming to solve matrix addition and multiplication problems and searching and sorting problems
• Apply programming to solve simple numerical method problems, namely rot finding of function, differentiation of function and simple integration

Question : 1  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);
if(n1<n2)
{
if(n1<n3)
printf("%d is the smallest number.", n1);
else
printf("%d is the smallest number.", n3);
}
else
{
if(n2<n3)
printf("%d is the smallest number.", n2);
else
printf("%d is the smallest number.", n3);
}
}
```
```

Question : 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.

```				```
#include <stdio.h>
int main()
{
char ch;
scanf("%c",&ch);
int lowercase_vowel, uppercase_vowel;

// evaluates to 1 if variable c is a lowercase vowel
lowercase_vowel = (ch == 'a' || ch == 'e' || ch == 'i' || ch == 'o' || ch == 'u');

// evaluates to 1 if variable c is a uppercase vowel
uppercase_vowel = (ch == 'A' || ch == 'E' || ch == 'I' || ch == 'O' || ch == 'U');

// evaluates to 1 (true) if c is a vowel
if (lowercase_vowel || uppercase_vowel)
printf("%c is a vowel.", ch);
else
printf("%c is a consonant.", ch);
return 0;
}
```

Question : 3  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);

Last_digit = N%10;
First_digit = N;

while(First_digit >=10)
{
First_digit = First_digit/10;
}
printf("Sum of First and Last digit = %d", First_digit + Last_digit);
return 0;
}

```
```

Question : 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.

```				```
#include <stdio.h>
int main()
{
int base, exponent;
long int result;
scanf("%d", &base);
scanf("%d", &exponent);
if(exponent == 0)
result = 1;
else
{
result = 1;
while(exponent != 0)
{
result = result * base;
--exponent;
}
}
printf("The result is : %ld\n", result);
return 0;
}
```
```
