c programming :

Question

i have written this program in C to get " n" (number ) first and then get "n "strings , compare the length of all strings and print the biggest one but the program wont compile please help :

#include <stdio.h>

#include <stdlib.h>

#include <string.h>

int main()

{

int n , i;

int max , maxlen;

scanf("%d",&n);

char a[100];

for (int i =1 ; i <= n ; i++)

{

scanf("%s",a);

}

max = 0;

maxlen = strlen(a[0]);

for (int i =1 ; i <= n ; i++);

{

if (strlen(a[i]) > maxlen);

{

maxlen = strlen(a[i]);

max = i;

}

}

printf("The longest is: %s with length equal: %d\n", a[max], maxlen);

return 0;

}

Answer 1

What are the compiler errors you are getting???

you have a semicolon after the condition in the if statement

inside the for loop. That is not necessarily a compiler error,

but definitely a bug

in the statement maxlen = strlen(a[0]), you must pass

the address!!! That is a compiler error...

Why not just do strlen(a); ????

The if-statement in the for loop is incorrect...

a[i] is the ith character in the string, which

is also a compiler error as strlen, again, expects

an address. Again, do strlen(a)

You did it again, a THIRD time, in the printf

statement.

============================================

#include <stdio.h>

#include <string.h>

#define MAX_LEN (1024)

void Go()

{

int N=-1;

int iLoop=0;

char str[MAX_LEN];

char inbuff[MAX_LEN];

while (N<0)

{

printf(" How many strings ???? :>");

scanf("%d",&N);

}

int maxStrLen= -1;

for (iLoop=0; iLoop<N; iLoop++)

{

printf(" Input the string :>");

scanf("%s",inbuff);;

int strLen = strlen(inbuff);

if (strLen>maxStrLen)

{

maxStrLen = strLen;

strcpy(str,inbuff);

}

}

printf(" The longest string is >%s< with length %d \n",str,maxStrLen);

}

int main()

{

Go();

}
