that one compiles and runs.... I can't get the second to compile.

#include <stdio.h>
int main (int argc, char * argv[])
{
int argcount=1; /* argv 1 is the first parameter */
int mode;
while(argcount < argc )
    {
    if(strcmp(argv[argcount],"-mode1") == 0)
        {
        argcount++;
        printf("mode 1 parameter = %s\n",argv[argcount ++]);
        mode =1;
        }
    else if (strcmp(argv[argcount],"-mode2") == 0)
        {
        argcount++;
        printf("mode 2 parameter = %s\n",argv[argcount ++]);
        mode =2;
        }
    else if(strcmp(argv[argcount],"-help") == 0)
        {
        argcount++;
        printf("Help mode\n");
        }
    else
        {
        printf("unknown command %s\n",argv[argcount]);
        exit(1);
        }
    }
printf("end of program in mode %d\n",mode);
}
