🚀 Programming Example
Nested if
Learn this program step-by-step with algorithm, source code, output and detailed explanation.
#include"stdio.h"
int main () {
/* local variable definition */
int a = 200;
int b = 300;
/* check the boolean condition */
if( a == 200 ) {
/* if condition is true then check the following */
if( b == 300 ) {
/* if condition is true then print the following */
printf("Value of a is 100 and b is 200\n" );
}
}
printf("Exact value of a is : %d\n", a );
printf("Exact value of b is : %d\n", b );
return 0;
}
Value of a is 100 and b is 200
Exact value of a is : 200
Exact value of b is : 300

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.
