I think the problem was the [ICODE]scanf[/ICODE] function you were using to read the floating point number.[ICODE]scanf[/ICODE] becomes a little bit upset if it doesn't get what it wants.Also use fgets instead of gets if you want to avoid another "segmentation fault" error.

I think you're highly mistaken about how functions work. 1.Why are you declaring all the variables as global ? 2.The compiler isn't your math teacher: [CODE]x=2(x1+x2); y=2(y1+y2);[/CODE] you should explicitly tell the compiler what to do(use '*' operator): [CODE]x=2*(x1+x2); y=2*(y1+y2);[/CODE] The brackets in c are either used to override the …

The problem is that you're calling the functions "getPoint" and "continueCraps" with either no arguments at all [CODE] getPoint(); // find the point ... continueCraps();[/CODE] or insufficient number of arguments.

IN line 17, the '%c' should be replaced by '%s' since name is a string(an array of characters) not a single char. Same thing in line 21 while using printf. Despite the above changes alot could go wrong with your program. Try using fgets() instead of scanf while taking strings …

since [ICODE]fgets[/ICODE] will not do what you're trying to do: [QUOTE][CODE]while(fgets(inarray,sizeof(inarray),stdin) !=NULL)[/CODE][/QUOTE] Because [ICODE]fgets[/ICODE] reads the chars in to "an array", and you're giving the address of "three" arrays ((3X3) means array of 3 arrays of chars) to it.

Obviously because you're reading each string from the file saving into a variable and printing newline('\n') after each one.[CODE]printf("%s\n",name);[/CODE] Don't you think this : [CODE]if(feof(fp)) break;[/CODE] is unnecessary since the [ICODE]while [/ICODE]statement already checks the condition and in addition it's preventing the last string from being printed out.

Sure.one way to do it is, put the whole program in an infinite loop and ask the user each time whether to continue or not. Check the user's answer if yes loop back else end the loop and exit.
