Write a simple code in C for multiplexer i.e. 2 bitmux there are 2 control i/p and 4 regular i/p Ex- A   B |   To   T1   T2   T3| output 0   0  |   1      X     X   X   |   1 0   0  |   0      X    X    X   |   0 0   1  |   X      1    X   X   |   1 0   1  |   X     0     X    X   |   0   X means ignore the input.   Write a simple code in C for multiplexer i.e. 2 bitmux there are 2 control i/p and 4 regular i/p Ex- A   B |   To   T1   T2   T3| output 0   0  |   1      X     X   X   |   1 0   0  |   0      X    X    X   |   0 0   1  |   X      1    X   X   |   1 0   1  |   X     0     X    X   |   0   X means ignore the input.  

Explanation / Answer

//Hope this will help you. #include void get_input(char *p,int *a) { do{ printf("Enter %s:",p); scanf("%d",a); }while(*a != 0 && *a!=1); } int main() { int a,b,t0,t1,t2,t3,output; get_input("A",&a); get_input("B",&b); get_input("T0",&t0); get_input("T1",&t1); get_input("T2",&t2); get_input("T3",&t3); if(a==0 && b==0) printf("Output = %d ",t0); else if(a==0 && b==1) printf("Output = %d ",t1); else printf("Undefined"); printf(" "); system("pause"); }
