\b;Exercise Destroy the six \l;targets\u object\bottarg; with a program using a loop. The bot must move 5m forward to get from one target to the next. \b;General principle The program must execute the following scheme: Repeat 6 times : o move 5m forward o turn 90 degrees left o shoot o turn 90 degrees right \image tfor1 14 5; \b;Instruction \c;for ( )\n; The instruction \c;\l;for\u cbot\for;\n; asks for 3 expressions: 1) Initialize the counting variable. 2) The end \l;condition\u cbot\cond;. 3) The counting \l;expression\u cbot\expr;. Here is the loop once it is integrated into the program frame: \s;\c;extern void object::Massacre( ) \s;{ \s; for ( int i=0 ; i<6 ; i=i+1 ) \s; { \s; \n;instructions repeated 6 times ...\c; \s; } \s;} \n; ATTENTION: The line \c;for ( )\n; must not be followed by a \l;semicolon\u cbot\term; ! \b;Explanation of the instruction \c;for ( )\n; 1) \c;int i=0\n; The \l;variable\u cbot\var; i is set to zero before the beginning of the loop. 2) \c;i<6\n; The loop will be executed as long as i is smaller than 6. 3) \c;i=i+1\n; At the end of every loop, add 1 to the variable i. \b;Blocks Use braces \c;{ }\n; in order to create a \l;block\u cbot\bloc;. All the instructions that must be executed in the \c;for\n; loop are held together by a block. The whole program itself is made up of a block: \c; \s;extern void object::massacre( ) \s;{ \s; \n;fill in here ...\c; \s;} \n; Never change these characters. Just add the instructions of the program between the braces. You can fit several blocks one into the other. For example the \c;for\n; block is fitted into the block of the whole program. In order to improve readability, the editor lines up the braces belonging to the different blocks. \b;Remember The instruction used to move forward is \c;\l;move\u cbot\move;();\n;. The instruction used to turn the bot is \c;\l;turn\u cbot\turn;();\n;. A positive angle turns left. The instruction used to fire the cannon is \c;\l;fire\u cbot\fire;(1);\n;. A one-second burst allows to destroy all six \l;targets\u object\bottarg;. \t;See also \l;Programming\u cbot;, \l;types\u cbot\type; and \l;categories\u cbot\category;.
