3.

What will be the output of the following programs V Ignore any syntax error. Write and Explain the output:

2*4=8

(a)

void main()

{int c;

int check(int,int); c=check( 10,20); printf(\n c=%d,c); }

check(int i,mtj)

{

int p,q; p⁼i; q=j;

if(i>45) return (p); else return (q);

}

(b) void main()

{

char str[]-Way of trouble is out through it; int i;

for(i=0;i<=3;i-H-) printf(%c,*(str+i)); for(i=0;i<=3;i++) printfl[%c*(str+l 8+i)); for(i=0;i<=13;i t i) printf(%c,*(str+4+i)); for(i=0;i<=9;i-H-) printf(%c,*(str+22+i));

(c)

void main()

{

int b[5]={2,4,6,8,l 0}; int i_t*k; k=&bf4l-4; for(i=0;i<=4;i++)

{

printf(%d\t,*k);

k-w;

))

(d) void main()

{

int ala2,c^s3*pl;

pt=&c; al=3*(c+5); a2=5* (*pt*5); printfC/odod, al,a2); }
