I am trying to compile c program with visual c++, but am getting this error: sampler_50_50_dbl.cpp(41) : error C2065: 'random_seed' : undeclared identifier sampler_50_50_dbl.cpp(42) : error C2448: '<Unknown>' : function-style initializer appears to be a function definition sampler_50_50_dbl.cpp(42) : fatal error C1004: unexpected end of file found can you help? following is my code: (it should split a file into two randomly selected parts) typedef double *renglon_fold; #include <stdio.h> #include <math.h> #include <string.h> #include <ctype.h> #include <time.h> #include <stdlib.h> #define MaxItem total_trn int matriz[2]; renglon_fold *matriz_da_or; int tiempo; time_t tiem; int num_trn; int maxstring; double *oldrand; /* array used in random no. generator */ int jrand; /* counter in random number generator */ double randomseed; /* random seed */ void advance_random() /* Create next batch of 55 random numbers */ { register int j; double new_random; for(j = 0; j < 24; j++) { new_random = oldrand[j] - oldrand[j+31]; if(new_random < 0.0) new_random = new_random + 1.0; oldrand[j] = new_random; } for(j = 24; j < 55; j++) { new_random = oldrand [j] - oldrand [j-24]; if(new_random < 0.0) new_random = new_random + 1.0; oldrand[j] = new_random; } } void warmup_random(random_seed) double random_seed; /* Get random off and runnin */ { register int i, j; double new_random, prev_random; void advance_random(); oldrand[54] = random_seed; new_random = 0.000000001; prev_random = random_seed; for(j = 1 ; j <= 54; j++) { i = (21 * j) % 54; oldrand[i] = new_random; new_random = prev_random-new_random; if(new_random < 0.0) new_random = new_random + 1.0; prev_random = oldrand[i]; } advance_random(); advance_random(); advance_random(); jrand = 0; } double random() /* Fetch a single random number between 0.0 and 1.0 - Subtractive Method */ /* See Knuth, D.

I didn't look in too deep, but it seem that removing the ";" at the end of line 42 should solve it. Let me know if not.
