So what trouble(s) are you having in doing so?

copy the string char by char and skip the spaces.

Watched code never compiles.

unsigned char pChar[100] = "i like vc++! "; printf("%s\n%s",pChar); it will compile and run..but it displaying 100 characters... 100 character means i like vc++ after null please help me any body

When your format string has two %s specifiers, you must have two parameters after the format string. So add one parameter to printf() or remove one %s from format string.

nothing here shows you are "trimming" the string; and there's an extra "%s" in the format part of printf.

Because Visual C++ doesn't like you. :rolleyes:

Hi. This litte program copys the string char by char and skips the spaces.

#include <iostream.h>
int count=0,count2=0;
int strLength=0;

int main()
{
unsigned char Cstr[100] = "this is a program";
unsigned char Cstr2[100] = "";

while(Cstr\[count\] != '\\0')
{
	  if((int)Cstr\[count\] !=32)	 
	  {
		Cstr2\[count2 \] = Cstr\[count\];
		  count2++;
	  }
		  
		count++;
  
  strLength++;
}
for(count=0;count<strLength;count++) cout<<Cstr2\[count\]<<"";
cout<<"\\n\\n\\n";
return 0;

}

unsigned char Cstr[100] = "this is a program"; unsigned char CstrS[100]; for (int i = 0, i2 = 0; i < 100; i++) { if (Cstr[i] != ' ') { CstrS[i2] = Cstr[i]; i2++; } else continue; }
