Foreword

It is a well known fact that passing AMIE is a Herculean task. The reason for thesame is multi fold. An AMIE student gets just notes and they have to themselves learn every

thing. AMIE students are working, hence no much time to study In the absence of class room training no continuous motivation. C being the toughest aspect for AMIE students as most diploma students

are scared about the same.

Due to these things I have thought of giving free discussions on various subjectsof AMIE. Section A & Section B (Electrical only).I intend to teach the subjects onSaturday and Sundays. Being an AMIE passed candidate I have thought ofhelping my fellow brethren with it. I can be contacted on

How to refer this Tutorial

This Assignments is designed for Computer and Informatics to

take care of C needs of AMIE students. Hence the no prerequisite

for these tutorials.

I intend to give you a compact and programming oriented approach

to C with hands on experience with some programs. Conceptually

it will meet the needs of students as a whole, but in addition to it, I

recommend to solve minimum five consecutive questions to get

the feel of programs asked.

A sequential reading is recommended for the first reading andsubsequently selective reading is recommended. But free of cost

contact program is recommended to understand these concepts. I

can be contacted for free of cost contact programs with prior

appointments.

6/8

/* the leading space before the %c ignores space characters in theinput */

scanf(" %c", &letter );

printf("Please enter a float variable ");scanf("%f", &money );

printf("\nThe variables you entered were\n");printf("value of sum = %d\n", sum );printf("value of letter = %c\n", letter );printf("value of money = %f\n", money );

}

TEST YOUR SKILLS

1. Use a printf statement to print out the value of the integer variable sum

2. Use a printf statement to print out the text string "Welcome", followed by a newline.

3. Use a printf statement to print out the character variable letter

4. Use a printf statement to print out the float variable discount

5. Use a printf statement to print out the float variable dump using two decimal places

6. Use a scanf statement to read a decimal value from the keyboard, into the integer

variable sum

7. Use a scanf statement to read a float variable into the variable discount_rate

8. Use a scanf statement to read a single character from the keyboard into the variable

operator. Skip leading blanks, tabs and newline characters.

Answers: Practise Exercise 3: printf() and scanf()

1. Use a printf statement to print out the value of the integer variable sum

printf("%d", sum);

2. Use a printf statement to print out the text string "Welcome", followed by a newline.

printf("Welcome\n");

3. Use a printf statement to print out the character variable letter


7/8

printf("%c", letter);

4. Use a printf statement to print out the float variable discount

printf("%f", discount);

5. Use a printf statement to print out the float variable dump using two decimal places

printf("%.2f", dump);

6. Use a scanf statement to read a decimal value from the keyboard, into the integer

variable sum

scanf("%d", &sum);

7. Use a scanf statement to read a float variable into the variable discount_rate

scanf("%f", &discount_rate);

8. Use a scanf statement to read a single character from the keyboard into the variable

operator. Skip leading blanks, tabs and newline characters.

scanf(" %c", &operator);
