And c++?

What will we do?C vs JAVADev-C++ tutorial and your first programC++ structureReading input/outputFlow Control (if, for, while)arrayfunction (method)debugging

Hello World (Day 1 Morning)C JAVA

import java.io.*;

class HelloWorldApp { public static void main(String[]

args) { System.out.println("Hello

World!"); }}

#include <stdio.h>

int main(int argc, char* argv[])

{ printf("Hello, CP!\n"); return 0;}

C vs JAVAC code DOES NOT need to be in a class

No filename restrictionC and JAVA have very similar syntax

if, for, while is the sameData type is almost the same (int, char, bool, float, double,

etc)Function and method is the same

For c++, function does not need to be in a class

We don’t really use any class in algorithm :D

Output (printf)printf(format_string, value…);

command What you get

printf(“YES”); YES

printf(“YES %d”,12); YES 12

printf(“%d is more than%d”,24,12); 24 is more than12

printf(“floating point %f”,2.3457); floating point 2.3457

printf(“test\ntest\nhaha”); testtesthaha

printf(“string %s is possible”,”haha”);

string haha is possible

input(scanf)scanf(format_string, &variable…);

Use the same format string

#include <stdio.h>int main() { int age, w; printf("Please enter your age and weight”); scanf("%d %d", &age, &w); printf(“your age = %d \n your weight is %d\n”,age,w);}

Condition Statement If statement

The same as java#include <stdio.h>int main()

{ int age;

printf( "Please enter your age" );

scanf( "%d", &age );

if ( age < 100 ) {

printf ("You are NOT old!\n" );

} else { printf ("You are old!\n" ); } return 0;}

While loopWhile loop

The same as java#include <stdio.h>

int main(){ int x = 0; while ( x < 10 ) { printf("x = %d\n",x); x++; } return 0;}

For loopFor loop

The same as java #include <stdio.h>

int main(){ for (int i = 0;i < 10;i++) {

printf(“i = %d\n",i); } return 0;}

Array in C++ (Day 1 Afternoon)(almost) the same as java#include <iostream>

int main(){ int fibo[100]; fibo[0] = 1; fibo[1] = 1; for (int i = 2;i < 100;i++) { fibo[i] = fibo[i-1] + fibo[i-2]; }

printf("%d\n",fibo[99]);

return 0;}

2D Array Example#include <stio.h>int main(){ int x; int y; int array[8][8]; for ( x = 0; x < 8; x++ ) { for ( y = 0; y < 8; y++ ) array[x][y] = x * y; } printf("Array Indices\n");

for ( x = 0; x < 8;x++ ) { for ( y = 0; y < 8; y++ ) printf("[%d][%d] = %d\n",x,y,array[x][y]); printf("\n"); } return 0;}
