if you just want to use file name without space then use this
FILE *fp;
char filename[40]; // you can use max lenght 260
strcpy(filename,"c:/");
printf("\n Enter File Name:");
scanf("%s",&filename[3]);
fp=fopen(filename,"a+");
int main(){
struct people{
char name[20];
short age;
} people;
struct people me;
printf("\n Write your name:");
fgets(me.name,20,stdin);
printf("\nHow old are you:");
scanf("%d",&me.age);
return 0;
}
ok now try this save your text.txt file (which you are trying to open in read mode)at a perticular location like at C or D drive and specify that location in fopen like this...
i watch your output my dear friend.. i think its working. you have already passed x[0]=3, that is why its not taking same 3 value in x[1], pass different value in x[1] and it will definetely prompt for x[2] and so on...
i think you program is just read data from the file and display the output on the screen, if its that simple then no need to use "char name [9999]" which is occupying 9999 bytes of memory. this could be done by just reading char by char from the file..
The vast majority of functions will give us some indication of success or failure. Especially with input it's best to make sure that the call succeeded before proceeding as if it did. In the case of scanf, a successful call will return the number of items converted:
okk... try this code, i made little change to your code..
#include <stdio.h>
#include <ctype.h>
int main()
{
char SubCode[30];
int week, student;
printf("What Is The Course Code? ");
scanf("%s", SubCode);
fflush(stdin);
printf("How Many of The Total Weeks? ");
while(scanf("%d", &week)!=1)
{
fflush(stdin);
printf("You Have Enter Out of Range\n");
printf("Please Re-enter Again\n");
printf("How Many of The Total Weeks? ");
}
printf("How Many Students In This Class? ");
while(scanf("%d", &student)!=1)
{
fflush(stdin);
printf("You Have Enter Out of Range\n");
printf("Please Re-enter Again\n");
printf("How Many Students In This Class? ");
}
return 0;
}
" i just create 1 exe file so that when i double click it. it automatically runs & produces the required output.although the s/w itself produces the exe file. but it opens along with all the supported/assosciated files with it. i just require only 1 exe file. "
i think kapil wanted to say when he is running that created exe file thats running well but its also opening the source code of that exe file. he just want to keep that exe file in seprate folder and when he or someone else click on that exe file only that exe file get executed.
# include <stdio.h>
int main(){
int a=10,b=3,reminder;
// suppose you want a%b.
reminder = a -(a/b)*b;
printf("\n\n Reminder of %d/%d is %d",a,b,reminder);
return 0;
}
This will also work like % operator..

In the loop i+j requires the addition of i and j in order to resolve the index into pWord. That takes unnecessary clock cycles. Just simply continue to use the i counter that already contains the value that is needed in the loop.
ya, your program is behaving so weird its because when we are pressing any alpthabet from keyboard its taking a garbage value..
int isalpha(int c);
The c argument is an int, the value of which the application shall ensure is representable as an unsigned char(0-255) or equal to the value of the macro EOF. If the argument has any other value, the behavior is undefined.
