The way if statements can be nested, similarly whiles and for can also be nested. To understand how nested loops work, look at the program given below: /* Example of nested loops */ main( ) { int r, c, sum ; for ( r = 1 ; r <= 3 ; r++ ) /* outer loop … Read more

Here a C program to calculate simple interest using for loop. main ( ) { int p, n, count ; float r, si ; for ( count = 1 ; count <= 3 ; count = count + 1 ) { printf ( “Enter values of p, n, and r ” ) ; scanf ( … Read more
For loop is probably the most popular looping instruction. The for allows us to specify three things about a loop in a single line: Setting a loop counter to an initial value. Testing the loop counter to determine whether its value has reached the number of repetitions desired. Increasing the value of loop counter each time the … Read more
It is often the case in programming that you want to do something a fixed number of times. Perhaps you want to calculate gross salaries of ten different persons, or you want to convert temperatures from centigrade to Fahrenheit for 15 different cities. Let us look at a example which uses a while loop. The … Read more
The programs that we have learned/developed in this tutorial so far used either a sequential or a decision control instruction. In the first one, the calculations were carried out in a fixed order, while in the second, an appropriate set of instructions were executed depending upon the outcome of the condition being tested (or a logical … Read more
The conditional operators ? and : are sometimes called ternary operators since they take three arguments. In fact, they form a kind of foreshortened if-then-else. Their general form is, expression 1 ? expression 2 : expression 3 What this expression says is: “if expression 1 is true (that is, if its value is non-zero), then … Read more
Since we have now added the logical operators to the list of operators we know, it is time to review these operators and their priorities. The higher the position of an operator is in the table, higher is its priority. The following figure summarizes the working of all the three logical operators.
In this article we will learn about the NOT operator, written as !. This operator reverses the result of the expression it operates on. For example, if the expression evaluates to a non-zero value, then applying ! operator to it results into a 0. Vice versa, if the expression evaluates to zero then on applying … Read more
Problem Statement: Write a program to calculate the salary as per the following table: Solution: /* C program to calculate salary */ main( ) { char g ; int yos, qual, sal ; printf ( “Enter Gender, Years of Service and Qualifications ( 0 = G, 1 = PG ):” ) ; scanf ( “%c%d%d”, &g, … Read more
