C program to find the eligibility of admission for an engineering course based on the following criteria.

#include <stdio.h>

void main()
{   int p, c, m, t, mp;

    printf("Eligibility Criteria for an engineering:\n");
    printf("Marks in Mathematics >= 65\n");
    printf("Marks in Physics >= 55\n");
    printf("Marks in Chemestry >= 50\n");
    printf("Total in all three subject >= 180\n");
    printf("or Total in Maths and Physics >= 140\n");
    printf("-------------------------------------\n");

    printf("Input the marks obtained in Physics :");
    scanf("%d", &p);
    printf("Input the marks obtained in Chemistry :");
    scanf("%d", &c);
    printf("Input the marks obtained in Mathematics :");
    scanf("%d", &m);
    printf("Total marks of Mathematics, Physics and Chemistry : %d\n", m + p + c);
    printf("Total marks of Maths and  Physics : %d\n", m + p);

    if (m>=65)
    
        if(p>=55)
        
            if(c>=50)
            
                if((m + p + c) >= 180 || (m + p) >= 140)
                
                    printf("The  candidate is eligible for admission.\n");
                else
                    printf("The candidate is not eligible.\n");
            else
                printf("The candidate is not eligible.\n");
        else
            printf("The candidate is not eligible.\n");
    else
        printf("The candidate is not eligible.\n");
}

Result:

Eligibility Criteria for an engineering:

Marks in Mathematics >= 65

Marks in Physics >= 55

Marks in Chemestry >= 50

Total in all three subject >= 180

or Total in Maths and Physics >= 140

-------------------------------------

Input the marks obtained in Physics :80

Input the marks obtained in Chemistry :80

Input the marks obtained in Mathematics :80

Total marks of Mathematics, Physics and Chemistry : 240

Total marks of Maths and  Physics : 160

The  candidate is eligible for admission.
