"Project 1-output bitmap"
Compose a program, use your name to pronounce the initials, make up a similar funny picture
650) this.width=650; "src=" http://img.blog.csdn.net/20150105150643968 "/>
Hint: printf ("... \ n"); The statement outputs the contents of the double quotes, ' \ n ' completes the line break
[Reference Solution]

"Project 2-Complete Simple calculation"
(1) programming, the input rectangle on both sides of the length A and B, the output rectangle circumference and area
Tip: The edge length can be an integer or a decimal, and the operator that implements the multiplication is *
[Reference Solution]

(2) programming, input two resistors R1 and R2 resistance, ask them in parallel after the value R
Tip: The calculation formula is r=1/(1/R1+1/R2)), the resistance value is floating point number
[Reference Solution]

(3) input Celsius temperature value (C), converted to Fahrenheit temperature value (F) and output
Tip: f=cx9/5+32, the temperature value to take the floating point number type.
[Reference Solution]

(4) programming, the input cylinder radius r and High h, the output cylinder surface area S.
Tip: Pi values are directly written 3.1415926
Sample input: 3.5 9
Sample output: area = 274.889343
[Reference Solution]

Item 2 Tip: The program that completes the calculation, its general structure is

#include <stdio.h>int main () {//define required variables//input data//data processing/output result return 0;}

"Item 3-crash exercise"
On the basis of the program that can run correctly, "trouble-making" makes some mistakes, compiles in c::b, observes and records error hints, and accumulates experience of facing errors.

#include <stdio.h>int main () {int a,b,sum;    scanf ("%d%d", &a, &b);    Sum=a+b;    printf ("%d\n", sum); return 0;}

Here are the errors that can be "made":
(1) Sum=a+b the 6th line; Remove the semicolon at the end of the line
(2) the 4th line int a,b,sum; int a, b;
(3) write the 7th line of printf as printf, noting that p and P are different
(4) Sum=a+b the 6th line; Changed to Sum=ab; The plus sign is missing.
(5) Delete the last closing curly brace of the 9th line of the program
(6) The 4th line int a,b,sum; instead of IMT a,b,sum; Note that the small hand may be a shiver, and int becomes IMT.
(7) You are a "bad" "Bad Boy" and think of "messing up" with your teacher.
