Logical Operators in C
An expression containing logical operator returns either 0 or 1 depending upon whether expression results true or false. Logical operators are commonly used in decision making in C programming. These operators are used to perform logical operations and used with conditional statements like C if-else statements.
&&
Called Logical AND operator. If both the operands are non-zero, then the condition becomes true.
||
Called Logical OR Operator. If any of the two operands is non-zero, then the condition becomes true.
!
Called Logical NOT Operator. It is used to reverse the logical state of its operand. If a condition is true, then Logical NOT operator will make it false.

#include <stdio.h>
main() {
int a = 4;
int b = 23;
int c ;
if ( a && b ) {
printf("Line 1 - Condition is true\n" );
}
if ( a || b ) {
printf("Line 2 - Condition is true\n" );
}
/* lets change the value of a and b */
a = 2;
b = 8;
if ( a && b ) {
printf("Line 3 - Condition is true\n" );
} else {
printf("Line 3 - Condition is not true\n" );
}
if ( !(a && b) ) {
printf("Line 4 - Condition is true\n" );
}
}

This Code is very simple and a good example of using conditional statement (if-else) in an iteration (i.e. for loop). We shall initiate a for loop having some finite iterations and check

This C program is used to find the sum of the 'Harmonic Progression Series'. H.P stands for harmonic progression. Harmonic progression is a progression formed by taking reciprocals
