Why is my nested while loop not working? -

i'm programming in robotc, vex 2.0 cortex. i'm using encoders make robot go straight.

this code:

void goforwards(int time) {     int tcount = 0;     int speed1 = 40;     int speed2 = 40;     int difference = 10;       motor[lm] = speed1;     motor[rm] = speed2;     while (tcount < time)     {         nmotorencoder[rm] = 0;         nmotorencoder[lm] = 0;          while(nmotorencoder[rm]<1000)         {             int rencoder = -nmotorencoder[rm];             int lencoder = -nmotorencoder[lm];              if (lencoder > rencoder)             {                 motor[lm] = speed1 - difference;                 motor[rm] = speed2 + difference;                 if (motor[rm]<= 0)                 {                     motor[rm] = 40;                     motor[lm] = 40;                 }             }             if (lencoder < rencoder)             {                 motor[lm] = speed1 + difference;                 motor[rm] = speed2 - difference;                 if (motor[rm]<= 0)                 {                     motor[rm] = 40;                     motor[lm] = 40;                 }                 tcount ++;             }         }     } }   task main() {      goforwards(10); } 

for reference, these pragma settings:

#pragma config(i2c_usage, i2c1, i2csensors) #pragma config(sensor, dgtl2,  ,               sensordigitalin) #pragma config(sensor, dgtl7,  ,               sensordigitalout) #pragma config(sensor, i2c_1,  ,               sensorquadencoderoni2cport,    , autoassign ) #pragma config(sensor, i2c_2,  ,               sensorquadencoderoni2cport,    , autoassign ) #pragma config(motor,  port1,           rm,            tmotorvex393_hbridge, openloop, reversed, encoderport, i2c_2) #pragma config(motor,  port10,          lm,            tmotorvex393_hbridge, openloop, encoderport, i2c_1) 

when excecute code, robot's encoder values close, robot stops moving when reach 1000. thought code wrote should return values of encoders 0 after reach 1 thousand, , thereby code should re-iterate in shell loop 10 times (in case). have done wrong?

you updating tcount @ wrong place. @ end of outer loop.

what have written makes tcount increase everytime moves ahead. time reaches 1000 steps, tcount 1000.

your times 10. `tcount >= time , wont enter outer while loop again.
