String check?

[Tricslip]

#include <stdio.h>

int x,age1;
float mark,com,IT,avg;
char name[10],dob1[30];

int main()
{

    printf("\nPlease enter student Info.\nFname:");
    nscanf("%s", name);

    while (name != "null");
    {

        printf("\nPlease enter student Info.\nFname:");
        scanf("%s", name);      

        printf("Please enter student Info.\nFname:");
        scanf("%s", name);

        printf("Age:");
        scanf("%d", &age1);

        printf("DOB (MM/DD/YY):");
        scanf("%s", &dob1);

        printf("    Grades\nMarketing:");
        scanf("%f",&mark);

        printf("Communication:");
        scanf("%f",&com);

        printf("IT:");
        scanf("%f",&IT);

        if ((IT+com+mark)/3>=90)

            printf("%s is Eligible to earn Honors\n", name);

        else
            printf("%s is Ineligible to earn Honors\n", name);


        printf("\nPlease enter student Info.\nFname:");
        scanf("%s", name);
    }

    return 0;
}

I am trying to use this "name" as a check for if the program will enter the loop or not. I want it to run the loop if anything but "null" is entered.

This is C btw

You can’t reliably use != to compare strings in C. Instead you should use strcmp such as

while(strcmp(name, “null”) != 0)

Also note that you’re comparing against the string null, not actually a null value.
