🚀 Programming Example
if- else important example
Learn this program step-by-step with algorithm, source code, output and detailed explanation.
#include"stdio.h"
int main () {
/* local variable definition */
int a = 100;
/* check the boolean condition */
if( a < 20 ) {
/* if condition is true then print the following */
printf("a is less than 20\n" );
}
else {
/* if condition is false then print the following */
printf("a is not less than 20\n" );
}
printf("value of a is : %d\n", a);
return 0;
}
a is not less than 20
value of a is : 100

First understand the algorithm carefully. Then study the program line-by-line and compare it with the output. Finally, review the explanation section to strengthen your logic and programming understanding.
Rewrite the program without looking at the code. Modify values, conditions or logic and run it again. This helps improve confidence and strengthens coding skills much faster.
