The following Program in C  prints the longest line in an input text using functions.

Program follows :

/*Program in C , using fucntions ,  to print the longest line in an input text*/ 

#include<stdio.h> 

int grabline(char newline[]); 

void copy(char from[] , char to[]); 

int main(){ 

char currentline[200]; 

char longestline[200]; 

int current=0; 

int longest=0; 

char c; 

printf("ENTER THY TEXT HITHER : \n\n"); 

while((current=grabline(currentline))>0){ 

if(current>longest){ 

longest=current; 

copy(currentline,longestline); 

                   } 

                      } 

printf(" \n\n THE LONGEST LINE IN THE INPUTTED TEXT FOLLOWS : \n\n"); 

printf("\n\n%s\n\n",longestline); 

return 0; 

} 



int grabline(char newline[]){ 

int count=0; 

char c; 

int i=0; 

for(i=0;((c=getchar())!='\n') && ((c!='\t'));++i){ 

newline[i]=c; 

++count; 

                                            } 

newline[i]='\0'; 

return count; 

                          } 





void copy(char from[] , char to[]){ 

int i=0; 

while((to[i]=from[i])!='\0') 

++i; 

                            } 

Sample Output :

hemant@hemant-desktop:~$ cd /home/hemant/code

hemant@hemant-desktop:~/code$ gcc test.c

hemant@hemant-desktop:~/code$ a.out

ENTER THY TEXT HITHER :

NEW LINE

ANOTHER NEW LINE

ANOTHER LINE BUT A BIG ONE

ANOTHER NEW LINE TERMINATED WITH A TAB KEY STROKE

THE LONGEST LINE IN THE INPUTTED TEXT FOLLOWS :

ANOTHER NEW LINE TERMINATED WITH A TAB KEY STROKE
