Write a c program to determine the operator precedence

program:

#include<stdio.h>

#include<conio.h>

#include<ctype.h>

main()

{

char str[100],ch;

int n=0;i=0,j,m;

printf("enter the line of text:");

do

{

scanf("%c",&str[i]);

ch=str[i];

i++;

}

while(ch!='/n');

//checking strlen(str);

for(i=0;i<n;i++)

{

ch=str[i];

if(!isalnum(ch))

{

switch(ch)

{

case '+':if(str[i+1]=='+')

{

printf("\n ++ is an arithematic operator");

i=i+1;

}

else

printf("/n +is arithmetic operator");

break;

case '-':if(str[i+1]=='-')

{

printf("\n -- is an arithematic operator");

i=i+1;

}

else

printf("/n - is arithmetic operator");

break;

case '*':printf("\n *  is an arithematic operator");

break;
case '/':printf("\n /  is an arithematic operator");
break;
case '%':printf("\n %  is an arithematic operator");
break;

case '<':if(str[i+1]=='=')

{

printf("\n <= is an relational operator");

i=i+1;

}

else

printf("/n < is relational operator");

break;

case '>':if(str[i+1]=='=')

{

printf("\n >= is an relational operator");

i=i+1;

}

else

printf("/n > is relational operator");

break;

case '=':if(str[i+1]=='=')

{

printf("\n == is an relational operator");

i=i+1;

}

else

printf("/n = is assignment operator");

break;

case '|':if(str[i+1]=='|')

{

printf("\n || is an logical operator");

i=i+1;

}

else

printf("/n | is bitwise operator");

break;
