How to skip reading something in fscanf - c

Question

If I have the following text file:
1 2 3 4 5 6 7 8 9 10 YEAH
11 12 13 14 15 16 17 18 19 20 YEAH
I have to following code:
#include <stdio.h>
int main(){
int arr[5][10];
FILE* foo;
foo = fopen("help.txt", "r");
int i, j;
int temp;
while (i<5 && (fscanf(foo, "%d", &temp)) !=EOF ){
arr[i][0]= temp;
for (j=1; j<10; j++){
fscanf(foo, "%d", &temp);
arr[i][j]=temp;
}
i++;
}
for (i=0; i<2; i++){
for (j=0; j<10; j++)
printf("%d ", arr[i][j]);
printf("\n");
}
fclose(foo);
}
...and it works perfectly fine when the text file has just numbers but when I add the characters "Yeah" to the text file, the code goes crazy. How do I include them? Please explain simply as I am still very new to this. Would I used fscanf(foo, %d%*c, &temp);??? Also how would I handle the new line statement if there is one?
Thank you very much
Edit:
the e input I provided initially was
1 2 3 4 5 6 7 8 9 10
11 12 13 14 15 16 17 18 19 20.
Here everything is printed out correctly. When adding the word yeah to the text file after 10 the all the other numbers are 10 as well. Essentially it does not contain 11 12... to 20. and prints out: 1 2 3 4 5 6 7 8 9 10
10 10 10 10 10 10 10 10 10 10

Answer 1

It is always easier to process data like this one line at a time, rather than one "token" at a time directly against the file.
Reading in a whole line with fgets() into a suitably big buffer, gives you the opportunity to take your time and go back and forth in the parsing, since it's all just bytes in memory at that point and you no longer risk confusion due to the file having a current position which is incremented as you read.
Your example conversion doesn't work, since you need something like "n numbers followed by something that is not a number, then end of line" which I don't think can be expressed as a single simple fscanf() conversion string.
Much easier to read in the whole line, then look at it token by token "by hand". See, for instance strtok() which is kind of dangerous in general but should be fine here.

Try this:
int e;
while (i<5 && (e = fscanf(foo, "%d", &temp)) !=EOF ){
if(e==0) {
fscanf(foo, "%*[^0-9]"); // this will skip the non numeric chars
continue;
}
arr[i][0]= temp;
and
for (j=1; j<10; j++){
e = fscanf(foo, "%d", &temp);
if (e==EOF) break;
else if (e==0) {
fscanf(foo, "%*[^0-9]"); continue;
}
arr[i][j]=temp;
