I'm very new to C language, I have the following code:
#include <stdio.h>
#include <stdlib.h>
int number;
int total;
int nums=0;
int i;
char c;
int main()
{

for(;;)
{
printf("please enter number here, and character k to quit:\n");
fflush(stdin);
scanf("%d",&number);
total +=number;
nums++;

}

printf("average value: %d\n",total/nums);
return(0);
}

Now I want is that when user type 'k' from keyboard, above loop will break.
Could anyone modofy my source code so that I can learn from you?
Thanks and regards,

Rather than use the for loop, use a conditional while:

cpp

int ch;

while (ch!='k') {
  printf("please enter number here, and character k to quit:\n");
  fflush(stdin);
  ch = getc(stdin);
  if(isdigit(ch)) number=ch;
  //scanf("%d",&number);
  total +=number;
  nums++;
}
