For those who are lazy to search through internet here is the link: gets() vs fgets() (http://faq.cprogramming.com/cgi-bin/smartfaq.cgi?answer=1049157810&id=1043284351)

I am greatly disappointed.

All your code do is assigning each element of your matrix to -1 and then display them. It is no surprise at all that you did not achieve the assignment because you haven't figured or aren't willing...

1. Why create this function when you can simply compare two characters with operator ==.

int Check_Characters(char s1,char s2) {
if(s1==s2)
return 1;
return 0;
}

Here is your code and its logical error.

int RemoveChars(char *S,char c) {
int i=0;
int spaces=0;
char temp;
for(i=0;S[i]!=0;i++) {
temp=S[i];
if(S[i]!=c) {
...

Not a good way :( but it works fine.


int sum(int num1, int num2)
{
int total, temp, temptotal;
total = num1 ^ num2;
for(temp = num1 & num2; temp != 0; temp = temptotal & temp) {...
