Question

Here I want you to be able to read a file which has titles of magazine articles and the page number they occur on in it.
I want you to ask the user for a page number, and give them the article which appears on that page number.

For example.

example.txt
10 The First Article
24 The Article After the first article
33 The Third Article
40 The Forth Article
54 The Last Article

program
>> Enter a page number
24
>> "The Article After the first article" starts on that page number

program
>> Enter a page number
65
>> No Article starts on that page number

Explanation / Answer

#include #include #include int main() { int n; printf("Enter a page number "); scanf("%d",&n); FILE *myfile; myfile = fopen("input.txt","r"); char *buffer; char *temp; temp=(char *)malloc(100*sizeof(char)); buffer=(char *)malloc(100*sizeof(char)); int t=0; int n1=n; int i,j; int found=0; while(fgets(buffer,100,myfile)) { t=0; n=n1; temp=buffer; while((*buffer)!=' ') { t++; buffer++; } buffer++; for(i=t-1;i>=0;i--) { if((int)temp[i]-48!=n%10) break; n=n/10; } if(i==-1) { printf("%sstarts on that page number ",buffer); found=1; break; } } if(found==0) printf("No article starts on that page number "); }
