Some time we need to take decision depending on some condition. Result will be true or false. If condition fulfil then result is true otherwise false.
For Example, student is Pass or Fail is dependent on their Percentage. Suppose Criteria is 50 %. So, student getting Percentage above 50 % then he or she is Pass otherwise fail.
There are 3 types of control statements :
Let us see one by one.
1. if -else
if(condn)
{
st.1;
}
else
{
st.2;
}
if(total>150)
{
printf(“pass”);
}
else
{
printf(“fail”);
}
—————————————————————
example,
if(a%2==0)
{
printf(“a is even”);
}
else
{
printf(“a is odd”);
}
=================================================
2 .nested if-else
if(condn)
{
if(cond2)
{
st.1;
}
else
{
st.2;
}
}
else
{
if(cond3)
{
st.3;
}
else
{
st.4;
}
}
————————————————————————-
example:
if(a>b)
{
if(a>c)
{
“a”;
}
else
{
“c”;
}
}
else
{
if(b>c)
{
“b”;
}
else
{
“c”;
}
}
=================================
3. else-if ladder
if(c.1)
{
st.1;
}
else if(c.2)
{
st.2;
}
else if(c.3)
{
st.3;
}
else if(c.4)
{
st.4;
}
else
{
st.5;
}
————————————————————————————-
example.
if(p>=70)
{
“A”;
}
else if(p>=60)
{
“B”;
}
else if(p>==50)
{
“C”;
}
else if(p>==40)
{
“D”;
}
else
{
“fail”;
}
