Hi,

#include <stdio.h>
char* RemoveLeadingSpaces(char* a);
int main()
{
        char str1[80], *ptr;
        printf("Enter a string upto 80 characters...\n");
        fgets(str1, 80, stdin); //gets(str1);

        ptr = RemoveLeadingSpaces(str1);
        printf("String after removing leading spaces is:%s", ptr);
        return 0;
}

char* RemoveLeadingSpaces(char* a)
{
        int i;
        while(1)
        {
                if(a[0] == ' ') //Comparing first character with space if it's equal copy remove first character in array.
                {
                        for(i = 0; a[i] != '\0'; i++)
                        {
                                a[i] = a[i+1];
                        }
                }
                else   //If first character is not space then exit from the loop
                {
                        break;
                }
        }
        return a;
}

In function i am just returning the string. If you want print in function then directly in a in function.

If you have any queries you can drop a comment....

Thanks...
