Predict the output

Predict the output of the following coding question on C language:

1. Find the output of the following code?

int main()

{

char *str = "hello, world";

char *str1 = "hello, world";

if (strcmp(str, str1))

printf("equal");

else

printf("unequal");

}

2. Find the output of the following code?

void main()

{

char *str = "hello";

char str1[5];

strcpy(str1, str);

printf("%s", str1);

}

3. Find the output of the following code?

void main()

{

char *str = "hello, world";

char str1[9];

strncpy(str1, str, 9);

printf("%s %d", str1, strlen(str1));

}

4. Find the output of the following code?

int xstrlen(char *s)

{

int length=0;

while(*s!='\0')

{

length++;

s++;

}

return (length);

}

5. Find the output of the following code?

int main()

{

char str1[20] = "C ", str2[20] = "Programming";

printf("%s\n", strcpy(str2, strcat(str1, str2)));

return 0;

}

6. Find the output of the following code?

int main()

{

char *names[] = { "A", "B", "C", "D", "E"};

int i;

char *t;

t = names[3];

names[3] = names[4];

names[4] = t;

for(i=0; i<=4; i++)

printf("%s\t", names[i]);

return 0;

}

7. Find the output of the following code?

int main()

{

static char str1[] = "C";

static char str2[20];

static char str3[] = "Programming";

int i;

i = strcmp(strcat(str3, strcpy(str2, str1)), "Computers");

printf("%d\n", i);

return 0;

}

8. Find the output of the following code?

int main()

{

static char s[] = "Hello!";

printf("%d\n", *(s+strlen(s)));

return 0;

}
