i have a problem, i can't see the output...
this is my program :
#include
#include
#define pi 4.0*atan(1.0)
#define BUFSIZE 300
int out_buffer[BUFSIZE];
void main()
{
int *output = &out_buffer[0];
int bits,samples_bit,a[6];
float bpsk;
FILE *fp;
fp=fopen("c:\\bpsk.dat","w");
a[0]=1,a[1]=-1;a[2]=-1;
a[3]=1,a[4]=-1;a[5]=1;
fprintf(fp,"1651 4 0 0 0\n");/*Header format of the data
file to be specified based on the data type where first
four digits are fixed so called Magic Number, since 4 is
mentioned as the samples are of floating point type*/
for(bits=0;bits<6;bits++)
for(samples_bit=0;samples_bit<50;samples_bit++)
{
if(a[bits] == 1)
bpsk0*sin(2*pi*samples_bit/25);
if(a[bits] == -1)
bpsk=-100*sin(2*pi*samples_bit/25);
fprintf(fp,"%f\n",bpsk);
printf("%f\n",bpsk);
*output++=bpsk; /*Output data writing to a buffer*/
}
fclose(fp);
}
how i can see the output?and i have an error, this is the error when i try to
build this program :
