i have to run a c program in linux but there's a getche() which i used in c program. how can i get rid of this getche() in order to run the c code in Linux. { /*some code*/ choice=getche(); }while((choice != 'q'));

info getchar

yea i have tried that but its not giving the output which i wanted....This is the actual code ...can u plz run it in C on windows...i want the exact output in Linux as well...the code is as follows:- /*This program deals with CAI (Computer Aided Instruction) which is often used to both develop and consolidate skills. This programming exercise involves the presentation of arithmetic questions to the user and provides varied feedback. The user h ave the option to choose a range of numbers to be used in the calculations; for example: single digit numbers or numbers up to 20. */ /*Author: Sukhminder Singh*/ /*Ver: cp728-1.0*/ /*Student ID: 2450362*/ #include<stdio.h> void getGrade(char); main() { /*declarations*/ int i,x,j,k,min,max,option,grade=0,total=0,totalques,range,true=0,false=0,reply,reply1; int choice1; char choice; clrscr(); printf("******************************************************************************"); printf("\n******************************************************************************"); printf("\n======================CHECK YOUR MATHEMATICAL SKILLS=========================="); printf("\n******************************************************************************"); printf("\n******************************************************************************"); printf("\n\nPLEASE ENTER A RANGE OF NUMBERS TO BE USED IN CALCULATIONS:");/*prompting the user for Range*/ printf("\nPlease Enter from -50 to +50:\n"); min=-51; do/*First do while*/ { do { printf("From What Number:");scanf("%d",&min);/*inputting minimum range*/ }while(min<-50);/*end of min do-while*/ max=51; do { printf("Till What Number Please...");scanf("%d",&max);/*inputting maximum range*/ }while(max>50);/*end of max do-while*/ }while(max<=min);/*end of First do-while*/ range=max-min+1; do/*main do-while loop*/ { x=rand() %10;/*using random function to randomise the switch case choices*/ clrscr(); switch (x)/*start of switch case*/ { case 0: case 1: case 2: case 3: j=random(range)+min;/*calculating the random value for inputing to the question*/ k=random(range)+min; printf("\n\tWhat is %d times %d ?

I don't have Windows so I'm afraid I can't run it. It looks like you'll need to replace the clrscr()s with system("clear")s, probably modify the random() calls and look at the Windows documentation for getche() and getch() so that you can replace them with equivalents from glibc. It can't be that difficult.
