1. Data Types
2. Variables And Constants
3. Operators

#include <stdio.h> int main() { int s1,s2,s3,s4,s5,total; float percent; printf("Enter marks of five sub: \n"); scanf("%d%d%d%d%d"&s1,&s2,&s3,&s4,&s5); total= s1+s2+s3+s4+s5; percent (total/500)*100; printf("\nTotal marks= %d",total); printf("\nPercentage= %f",percent); return 0; }

Output:

Enter marks of five sub:
84
76
65
90
70
Total marks= 385
Percentage= 77

Description of Program:

• Input marks of five subjects in variables that say s1,s2,s3,s4 and s5.
• Culculate sum of all subject and store it in total. i.e, Total= s1+s2+s3+s4+s5.
• Divide total marks of all subject by total number of subject or divid total marks of all subject divided by 500 and multiply them by 100 to find the percentage. i.e,  (total marks/5)= %.  Or (total marks/500)*100= %
• Overall, print the total values and percentage.
