# C programming for the beginners | problem | solution ANSI C balagurusamy | chapter 1(1.7)

In AnsiC balagurusamy problem no 1.7 in chapter

1 given two integers 20 and 10 write a program

that uses a function add() to add these two numbers and sub() to find the difference of

these two numbers and then display the sum and difference in the following form: 20 + 10=30

20 – 10=10 we will use two function add and sub by this

we will take two integer 20 and 10 which will show in the display

so go to the program now its similar to the privious lecture

there will #include , main function then we will take two integer

by int a ,b ; now we will take two function add and sub

where sum will show in add function and in sub funtion we will see the subtraction

now as a and b are given so we will define that

so we have to show in this format so now we will print

by printf as the two addition are shown by add

same process in the below you can give return zero

now its time to run there is a problem

as we define these two values again run

so we get our result but in one line and one more problem

we have to define these previously and there give n

now run here is our result we will see the other problem of balagurusamy
